About jetlasers

Hello all . Im eyeing on afew lasers for sometime and need some tips on if i should get it .

- Jetlasers 4W PL-E Pro 445nm Blue Laser
445nm PL-E Pro 3.5W, 4W, 4.5W and 5W Lasers, PL-E Pro 445nm blue Laser

- Wicked lasers S3 Artic 2W
Spyder 3 Arctic Blue Handheld Laser


I heard that WL lasers do last long and is very durable , I was wodering if the JL does too .

How long does the battery last on the PL-E Pro 445nm Blue Laser ? It runs on 2 x 18650 lithium batts.

Both prices are rather high but im wondering how long the PL-E Pro 445nm Blue Laser run cycle is? Im afraid the diode will die on me (all about the heatsinks i guess) . The Artic did state that it can run 24/7 .

And how can i tell if the product i received is Overspec / Underspec ?

Please give your opinions on which i should get . Both are really pricey though :/ Coupons would be greatly appreciated for JL/WL

Thankyou

well constant duty cycles are a lie unless there is active cooling. I promise an arctic 2W at full power left on will kill the diode eventually. how long the battery lasts depends on which batteries you use, silly. where do you live? WL does not ship to u.s. any longer. If it were me, I would have one custom made or make one yourself, it's pretty easy and rewarding, and custom ones can be just as inexpensive or expensive as company bought ones. have you had a high powered laser before? 4W before even say, 1W, is like going shooting for the first time and reaching for the RPG instead of the .22. I cannot emphasize the damage these are capable of enough. much less than 1W could instantly blind you. 4W could blind you and burn a hole in your frontal lobe. not really but you get the point I hope

I did have a PL-E pro 4W diode die on me, though I think I didnt let it cool off enough. they get hot quick

Thanks for your quick response I live somewhere in asia I have never built my own laser before but i have owned 1 , 1.5w laser before (lastyear)

I have been interested in lasers ever since . My previous laser died on my because of overheating and dead diodes . Probably why im so particular about long lasting lasers . Can't waste much money on these . only 18 and schooling

Anyhow , if i were to build my own laser , i doubt i'll be able to make a 4w / long lasting one .

Lets say i get the JL . Will it be okay if i just turn it on and off for like 2minutes? (Run cycle 2mins on/off) ? Or maybe a shorter runtime an a longer cooldown ?

ps. I was really impressed by the JL mostly because of this : https://www.youtube.com/watch?v=QDoc8d9NRb8

10m(s) Wow.

i have watched many JL videos on the specific laser im eyeing on just to see how long they actually run it for . (11mins video longest so far) Im sure its just not the right way to judge , gosh

well I have since built a custom laser using the same diode. mine is well encased in a 1 troy lb copper heatsink, and I still can feel warmth after a few minutes. I know the heatsink on the JL must be much smaller. unless you want an easy beam expander add on, If I were you I would just contact Blord on here and have him make you a copper Dominator using the NDB7A75 diode. ask if he can put on a short module back-half for better heat transfer. if he doesnt have them, you could ask DTR to send him the module-driver-diode-back half setup to use. you'll have to pay different people but the result will be worth it. Here is the heatsink of mine compared to a 501B copper heatsink. this is just what I did, there are many ways to "skin the cat"



here is the old version. the module in this pic lacks the back half i mentioned



adding one of these, shown on the far left in this pic, will help greatly (hope you dont mind DTR)

Damn , they look really cool O:

Looking forward to build my own laser so soon already

I have contacted B'LORD to purchase his Dominator 3w-3.5w . Hoping to get his reply soon . hehe .

well the thing is, his 3-3.5W version uses the NDB7875. I believe the 2W PL-E pro uses the same diode. why is theirs only 2W? because it is driven at a lower, safer current. the 7A75 diodes are more powerful, and a bit more expensive. but, a 7A75 diode can put out 4W without being overdriven as much as the 7875 is when doing 3-3.5W. the 7A75 can in fact be overdriven to as much as 6W, but with any diode, the harder you drive it, the shorter will it's life be.

to be specific, the 7875 diode is designed to handle 1.7A, but Blord's build will drive it somewhere around 2.4-2.5A

the 7A75 diode is designed to handle 3A, DTR's supplied driver pushes it to 3.5A

so the 7875 is overdriven by about 41% whereas the 7A75 is overdriven by about 16% big difference if longevity is your goal these are things to consider

I speak from experience. I also once had a 3.3W dominator, the diode lasted a while but it too died. my current build uses that heatsink and host with the new diode and DTR's back half, it is going strong with no signs of giving out any time soon.

That explains a lot ! Wow .Didn't know there's such thing like this .

How would you recommend me to build my very own 3.5 - 4watt laser that could have a long Run cycle (about 3-5mins) with a wavelength of 445nm? Without over driving it too much of course .
No wonder lasers on official sites are way more expensive . They did actually state the lifetime of the diode . etc : >5000 hours or something .

So now what I'm aware of is the higher the watt the more expensive it is if you don't want to overdrive it too much for longer lasting diode . And a good / bigger heatsink for longer run cycles .

I still don't get all the other things like the driver and what kind of glass and how to make a focusable laser . o: I wouldn't mind following your instructions on how to make one long lasting laser that meets my desire spec

you will have to make the choice yourself. we can answer some questions and many can be answered by searching around here.

since you said you are interested in something long lasting I thought I'd make you aware of some factors that effect that. the nice thing about having one custom made is that it's often possible to chose the current it is driven at, so you have more control over how hard to be on the diode. I personally do not like replacing diodes so most of mine are driven less hard than other builds common here using the same diodes.

DTR's website is helpful as it shows average power outputs one could expect from various diodes at different currents using a single element glass lens. there is a lot to learn but you will be better off learning it all first then chosing rather than making a choice and being unhappy with it later. If you have a question, try searching for it using the google search bar at the bottom of the page. if after some searching your question is unanswered someone may be able to answer it, though chances are high every question has been answered before and can be found by searching

about focusing, it's actually less common to see fixed focus lasers than focusable ones. other than 532nm dpss and other DPSS wavelengths, and even some of those are focusable

By the way , Shakenawake. How long did your dominator 3w laser last you ? and on average how long do you use it a day ?

Thanks for all the knowledge . I'm sure I'll build one soon . I'll search up for guides around here . Went pass a few some time ago . I just like to be spoonfed I prefer a personal " Teacher " For this kinda stuff . Selfish me x:

I don't remember how long it lasted, but it was too short to me. I used it only a few minutes each day tops. there's no way the diode even had 100 hours total on it when it died. well it actually degraded, didnt die, but to me a degraded diode is a dead diode. my 4W pro did the same, degraded to 1.3W.

It's possible Blord could make one set to a lower current, you'd have to ask him

zeds, your post is not really helpful and borderline spam if not spam. the fact it is your only post seems to bolster this. it appears to be copied from their site, which I'm sure OP has seen

I see . I guess I really have to get a LPM machine thingy too huh .

How do you even adjust the watt anyways . I see a lot of voltage and current meter on pictures . What does it got to do with the Watt .

Not mentioning some who talked about stability ?


Seems like The amount of current voltage affects the watt and things have to be increasing and decreasing stably . am I right ?

Let me guess... You can program your driver to take in amount of Current to produce amount of watt.. ?

more current=more watts=shorter life

diode lasers are very stable in power output as opposed to DPSS lasers. seriously though do some searching, we are loathe to do too much spoonfeeding

Sure Thanks a lot for the headstart

What you heard is totally not true. Their laser is overpriced and VERY poor in quality. Furthermore, their customer support is crap and shipping is super long.

If this is your first laser, remember to get laser safety google. i would recommend you getting from here

One thing to consider, although less stable, a DPSS 532nm laser is 20 times brighter to our eyes than 445nm blue. This means a 100mw or 1/10 of a watt 532nm green laser is just as bright as a 2 watt blue laser, although wont burn as well.

Anyhow, I heard 445nm laders have a huge divergence right ? Meaning it wouldn't burn at long distances .

I'm sure some of you have seen the WL video on it pooping 100 balloons . If I were to build a 3w 445nm laser will it do the same with G2 lenses ? or maybe a 3 Element glass ?

Does WL 445 laser have the same divergence ?
