Review: 473 nm 100 mW Jet Lasers PL-E Pro „Sky Beauty“
After some time using this amazing laser I would like to do my first review here on LPF for you. I do not have LPM therefore I realized to do the review by my own way according to my use. You might find another reviews here where there is a lot of great information and experience with this laser. I took also several shots of the laser and stuff. Some of them are taken with my digital camera, some with my mobile phone cam. All pics are clickable leading to higher resolution. If you miss some information there, do not hesitate to ask in comments.
Enjoy...
Selection
Not only I always wanted 473 nm wavelength in my collection, I wanted also portable and highest power and the best beam specs for purposes of laserpainting. Quite contradiction in my demands. However luckily this laser has them all. It’s DPSS with very ineffective process therefore 100 mW is quite a lot. In deed I do not believe it is only 100 mW, I have seen the same laser from different member here to do over 200 mW (source: Razako's review). I also did not wanted 465 nm which could give you watts of power and the color should be very similar, it’s diode and beam specs are not as good as with DPSS. In addition for my purposes I needed the longest possible duty cycle, that was reason why I went for Pro and not Mini – larger host, therefore better heatsinking. In addition you might select between silver and black finish, where for practical reasons of laserpainting and my liking as well I selected the black version.
Also to mention LPF community here helped me with valuable advice to get to JL, which I completely omitted to include to my company selection. Thanks, the best choice.
Customer experience and shipping
I have contacted JL customer service and Gray responded to me quite fast. We discussed my needs in detail and he (and JL team) spent a lot of time finding a solution for me. There was even option they could make me custom module powered by accu pack to keep long duty cycle. Still I found this solution quite bulky for my laserpainting needs. All at all after thought decision I selected my original choice finally. I went for mechanical switch as the code switch is not recommended due stability issues. All my customer experience with JL was the best I had so far. Only fail was with DHL or JL's shipping agent, which caused extreme delay. After contacting Gray he found out what was wrong and got it working – they were so nice, to refund me full shipping cost for „inconvenience“. The total time was since 15th March ordered till 5th April to be in my hand. When I ordered the laser I asked to have both tailcaps, AC adapter, beam expander and remote switch. Gray was so nice to sent me extra tailcap and remote switch for free.
Overall experience is: JL customer care is outstanding, Gray will do everything for you and is able to respond in times when normal people sleep deeply. This guy is extra caring and friendly. JL has real valuable asset in him.
Packaging
I think it is part of the product, as when shipping is not done properly, the risk of laser being damaged during transport rises. So, here you can see what you can expect with your JL order:
(mobile cam pic)
Package arrived in classic yellow DHL sack with shipping documents attached to it.
(mobile cam pic)
Inside was in wrap foil well packed box with the stuff inside. You can imagine the size of the box with comparsion with my Zippo lighter (standard size).
]
(mobile cam pic)
I noticed they packaged it very carefully.
(mobile cam pic)
After removing the foil there is a very nice paper box...
(mobile cam pic)
...with chart showing wavelength stability on the back. I’m not sure if it is for my particular laser, or for these in general (I think it is likely as I would expect individual test on separate paper).
(mobile cam pic)
Inside the box is well fitted Christmass.
(mobile cam pic)
JL even care to put extra foam pad at the bottom.
(mobile cam pic)
Here all the stuff packaged individually.
(mobile cam pic)
Laser itself and all the parts are packaged in antistatic bags in addition.
(mobile cam pic)
You can notice the laser came dissassembled in two parts and see the plastic batt reducer for 18650.
Overall this is the best packaging I’ve seen so far. Only a bag of silicagel was missing there, but no humidity could pass this packaging anyway.
First tests
After I got home, I did first tests – see here:
(mobile cam pic)
The beam.
(mobile cam pic)
The dot at daylight.
I of course tried some burning. It lit up a cigarette in about 30 seconds at the distance of about 4 meters, focussed to infinity. I used Panasonic 18650A batt for it. After warmup it is incredibly bright and powerfull, definitely more than 100 mW. The dot is nice round TEM00. The output beam diameter is about 1 mm and divergence below 1 mrad (as JL say – I did not measured it properly, but compared to my other lasers it seems to be true). If the laser is running in the enviroment of temperature above about 25 degrees Celsius it switches to near TEM00 or TEM01. But only if running longer and warms up too much. I’ve never ran it to be really hot to touch, so I cannot say how it will come out. After it is cold again, it returns to TEM00. The laser heats quite a lot, therefore cooling is needed – with environment temperature in reasonable range or keeping it off for a while. But it is a much better duty cycle than I expected. The output power stability is higher than I expected as well, still it is not as stable as my 589 nm Dragon Lasers Spartan. But it is not a problem at all. And yes, my laser likes it a bit warmer, but not too much.
The Laser
This host and laser was described here in other reviews, so here I’ll take it briefly. The host is pretty large, much larger than WL Spyder, which looks like a toy next to it. It is well bulit, with smooth threads and quality finish. You can choose to use one 18650 batt with reducer (or battery condom as one member calls it in his review) or one 26650 batt. For flat top, JL included three small neodymium magnets as well. Batt comes negative pole first, as drawing on host shows (good to have).
The host has momentary and continuous buttons, both working perfectly. Before you need to switch on the power supply with button (or standard laser key – depending on tailcap you have) and three leds next to buttons start glow red. After you fire it the led(s) turns green (in case of constant on button and by brighter blue for momentary - I personally would switch them), which is not visible usually with goggles for blue, but not a problem at all.
The aperture has threaded protection cap with hole on it to be tied with bezel as you can see. The aperture window (according to JL it is also IR filter) is good to access for potential cleaning.
The laser is focussable with scale and mark to remember position of focus. As every laser will be individual with infinity you need to play with it to find right focus position. The focus ring is turnable, but the bezel is static, with combination with quite tight focus ring it is not likely to come out of focus with manipulation.
At the bottom you can find from aperture side – 3.5 mm jack for remote switch, 5 V DC input from the AC adapter and threaded hole for tripod, which is not very deep for common tripod „bricks“, but you can always use clamped solution.
To add there are also holes on bezel and tailcap for attaching lanyard (supplied with laser), protection cap etc.
Entire host has a very nice design, with knurling to keep firm hold.

My experience
My experience from use is mainly from laserpainting. The laser is easy to handle and it is important to know it well to manipulate it in low or almost lack of light conditions. Not a problem. Tailcap switch and push of button do the job. Momentary button is smaller, therefore there is no problem to distinguish them with finger. In addition I sometimes use also the remote switch for which I got standard jack-jack extension with jack female-female adapter. Works perfectly.
However supplied remote switch works like push-to-click to swith it on after release. By touching it you can switch it off momentary and by release it turns on again. If you want to switch the laser off completely, you need to do push-to-click again.
With remote switch I can keep laser on static position, be out of scene or no eye safe zone and switch it on on my demand. Awesome feature.
It is also good to ensure operating temperature is kept. If laser is too cold it gives just a little of power, if it is too hot it jumps out of TEM00 as I mentioned above. I once did not realized the low output at low temperatures (was not that low at all a lot above zero) and it was not good, I had to switch it off and make it slowely warm to prevent moisture and thermal shocks. Now I keep it wrapped in bubble foil to be sure it is kept warm – no problem since then.
The aperture threading is exactly the same as threading of WL Evo laser, therefore I’m able to use my Evo expanded kit with it (with all kits features metioned in my laserpainting thread), although it is quite hard to fit it due little space inside the bezel ring. With supplied beam expander comes also quite smart adapter. This adapter is composed of three parts. One is to be mounted to laser one to the beam expander and third screws both parts of the adapter together. You can adjust the beam position with it or use only part attached to laser to mount some optics on it more comfortably – I use WL Spyder expanded lens kit to fix it to the third part of the beam expander adapter with a piece of duct tape and screw it onto the part mounted to laser. Much more convenient solution.
Also the protection cap is sometimes hard to access, but I have small fingers, so not a problem, but for someone with larger fingers there should be some extentsion of the handle considered.
And finally, the color - 473 nm is short wavelength scattered quite a lot in the atmosphere, therefore finding focus position requires a while. But once you get it, it is awesome needle thin beam with turqise blue center and kind of darker at the edges reminding my 445 nm – royal blue. The similar it is with my 589 nm, the edges looks a bit more orange. I like to give my lasers names, this one is Sky Beauty. Just look at the pics below and you will find out what I mean.
Beam shots
Here I took some beamshots for you (mostly after a sunset):
(digital cam pic)
At my garden with my sister’s/our dog really wanting to be at the picture (no joke, he refused to leave me alone with the laser before I took pic with him on it).
(digital cam pic)
The beam through the tree without the dog now.

(digital cam pic)

Artworks
As I mentioned my use of this laser for laserpainting artworks, you can see some of them I did so far below. For more see my laserpainting thread – link to thread and the latest laserpainting are always in my signature. For your convenience I attached links leading to that particular artworks under the quoted posts.
Here you can see the laser creating a flat surface hitting the sphere and simulating sky, with this composition it looks a bit shorter wavelength as royal blue.
In this laserpainting the beam comes through both worlds showing the path. Here I played with the edges and center differences to create kind of wave look around the beam.
A few words about accesories
Laser comes with manual info material, warranty sheet, quality check card, with magnets for flat top batts, battery reducer, lanyard and microfibre cleaning cloth and simple battery charger (I did not try it as I have more advanced XTAR charger). In my package I got also key lock tailcap with two keys and remote switch in addition to 10X beam expander and AC adapter ordered.
I just did not mentioned beam expander as I have tested it only briefly. The input is quite narrow, but for this laser beam diameter sufficient, output lens is great with noticeable AR coating looking like a yellow mirror. However I did not find how to adjust focus on the beam expander, it looks like the ring is fixed. It looks for Mini version it might be really focussable, but Pro version does not look like focussable. Also good to mention – focus is not zoom. The problem is rubber protection cap of the output lens of the beam expander, which holds dust and fall off a lot, but Gray told me they will be likely replacing them. The protection cap for input lens is none, but this is not as problem at all. If I compare it to Dragon Lasers beam expander, with two metal threaded protection caps for both ends, this one I like more. Still the beam expander looks to be a high quality. What I like is adapter, where you can adjust the beam position as I described above in My experience part.
Regarding AC adapter. I did not tried it yet as it was delivered with US plug, so adapter is needed – not a big deal, I was just too lazy to find it. JL should deliver some adapter for that, according to discussion with Gray. It supports inputs AC 100 - 240 V at 50 – 60 Hz and delivers output DC 5 V at max 4 A, therefore your phone charger might not be sufficient if you consider to use it instead. As it is double insulated, there is no ground pin on input.
Conclusion
This laser is worth every cent. For 473 nm 100 mW with described beamspecs and for the price of 400 bucks I’m not aware of any better option. If I consider this as complex product (including customer care and problem solving) the value you get is much higher. You cannot go wrong with JL. And thanks Gray for great service provided. There are only little cons, which are not really important even to mention here.
It is another true jewel of my collection. And I’m looking forward to further nice time spent with this laser.
Overall I highly recommend to consider this laser for anyone interested in 473 nm portable.
Just one note, consider that every DPSS laser is different, but what I’ve read here on LPF, these dildas like it a bit warmer and give a very overspec output.
Final note
It was also a lot of fun to share with others on LPF our feelings when waiting and receiving the JL products in several threads. It made me the waiting a bit shorter. So, thanks.
Bonus for those who finished it here
And here is bonus comparsion of size with my entire collection of portables:

The Portal
How do I see the way into surreal world? The essence of reality is interaction, the collapse of in quantum mechanics so called wave function...
In this laserpainting the beam comes through both worlds showing the path. Here I played with the edges and center differences to create kind of wave look around the beam.
