Deciding between Sanwu and JetLasers

I'm looking to get a green laser that's smaller than the standard PL-E Pro, so i'm looking at the PL-E Mini in 700mW 532nm or 1W 520nm. However, i'm also looking into Sanwu's stuff for the first time since I hear it's a good company and the Challenger 2 seems like a good pick as well. The main thing i'm wondering is how the models compare in terms of size, battery life, and heat. Any info?

Yes, to what Alaskan stated ^^^^^ above, they're both great companies with top notch high quality products.
I also don't own a Sanwu pointer yet, but I've got their 3X BE, and other accesories like their light saber attachment, and they're high quality products.

It really just comes down to personal preferences, like which look do you prefer, and duty cycles; how long do you want to run it.
The Sanwu Challenger ll is 24mm x 140mm, and the Jetlasers Mini is 34mm x 230mm, so I've got to imagine that you'll get a bit longer run times with the J/L.

I don't think you can go wrong with either one of these choices! :yh:

I own both, JL and Sanwu. Very satisfied with both. JL will be longer and make’s it difficult to carry in your pocket. Sanwu’s got a leg up if you prefer a laser you can carry in your pocket. But Sanwu doesn’t make a 532nm, if you were looking at that wavelength. Either way you should be most happy.

Ps, after your purchase, beamshots work quite well. (hint,hint) :)

Thanks for the replies. I had a PL-E Pro 1W 520nm in the past and I was happy with it, so I think i'm gonna go with the Mini 1W 520nm and get a Challenger 2 in 1W 635nm since I haven't had a red in ages.

As others have said, both companies have high quality products. Sanwu is better for portability, but if say jetlasers is better in terms of value and heat sinking. They also offer 532nm dpss lasers, which sanwu does not. These will have better divergence than diode alternatives.

Hope you enjoy whatever you decide on :beer:

Sounds like a plan, get one from each company. :yh:
The 635nm will be a nice change of pace, you just don't see reds getting much attention these days.

Be sure and share with pics when you get these beauties! :D

That 1 watt 635nm laser will likely have very bad divergence specs as it probably use either the Mitsubishi P73 or the Oclaro diode. Both look more like a line than a dot. If I were going to buy either the Jetlaser or Sanwu, I would pick the Jetlaser as it has better heat sinking and more battery room for longer run times.

I like Jetlasers myself, but have never owned a Sanwu pointer, however judging their 3.3x beam expander, I am impressed with its quality.However, you can’t go wrong with a Jetlaser quality either, and their DPSS pointer divergence for 532 nm is great. For the same divergence from a 520 nm direct to wavelength diode, you need a 3 x beam expander, but then the beam is fatter. I don’t mind that myself, 3x isn’t so much.

I wish either company would make or source a 5X 6X or 7X beam expander with an 8mm input and 40 to 50mm output AR400-700 for our favorite MM beams, quality like the Jet 10X would be worth 200.00 each and I would buy many.

The 3.3X is a favorite but the threads can develop some play, the Jet 10X adjuster is proper, if the input and output were just wider I would buy many and happily at twice the current price.

Yea sometimes the beam is off center from the module, other times it's just fine, you can tell by looking at the print on the output lens, this one is a NDB7A75 I pressed into a 12mm module myself with a G7 lens then the 3.3XBE, it looks good. The 2nd pic is a NUBM44 in a 12mm module with a 3 element lens then the 3.3XBE.

These are both centered, but I have seen the print end up off center all because of how the diode seats.

This gives me hope that the 12 mm modules will work out for the single 44 build. I never have trouble seating a diode into one. I have pressed many, many diodes over the years. There was a short period when the modules from DTR weren't seating properly, but I brought this to Jordan's attention and he made good on all of them.

Yes, the heat sink Rich will be making us will have only 4mm of wall thickness so it will need a short set screw, I have some short 4-40 set screws that BowtieGuy sent me that I was thinking about using if I drilled out a 20mm aluminum back half with a 12mm drill but I want to use the driver shelf the heat sink will have, or a 20mm with the driver cavity in the back half.....if possible.

both are good choices.. I see that JL no longer offers any EQ except whats left-but they are nice- 1.4W 462 sky blue-its focus is set (well imho) grey host 3mm at ap. 2mRad. 'Not B.E. ready.' uses 2pcs 16350s afaik JL still ships for $38 DHL crazy fast express..
$189.99..

otherwise-- Mini Pro Pl-E 520 1W $270 2.5mm at ap-2mRad-1W--
Mini Pro PL-E 532 700 mW 2.5mm at ap 2mRad $400. (600mW $330.--500mW $290.
^^ both are B.E. Ready add only $90 for matching color BE
I would search around for any members selling (WTB) and for any coupons/codes/ etc-- afaik the $15 off is over--sry.
