i was search the 896nm diode, i can't find anythings.

anyome know it 896nm diode?


incorrect information.

Update : 577nm(571nm family), use 940nm.IMG_20210803_164109.jpg

Not sure I trust that info from their sales rep without a spectro graph... every other module Lasense does is 808nm pumped, and I would expect the 57Xnm modules to be no different. (I do not own one of their 57Xnm modules to verify... but I would put money on it being 808nm). I would be more than happy to verify that if anyone has a spare.

Lasence 545nm:


Lasence 559nm:



However, every module their competitor OPTlaser produces is 940nm pumped.
OPT 565nm:


OPT 572nm:

Do you have any specs on the opt laser module? Lasence states Bad beam specs and multimodal operation. I can order a module at 100usd at the moment and I don’t trust them, seems like they got quality problems.

it is actually pumped by 940nm

here it is. there was a bit of dust scattering the light, thats why the spectrum for the 575 was so large

Oh.... O_O

I can find the lot of information about the 57x yellow laser through these forums and threads. Thanks everyone.
i have alot of information about them, ive been doing research on them for some time now. lasence told me that it isnt Nd:SVAP

Interesting, thanks for the graph. Very odd, I figured they'd use the same process for everything but I guess they actually do have multiple processes under their belts.

well actually, there older modules used 980nm and some engineering sample modules use 900nm, ive owned all 3 variations of the modules btw the crystal is NOT Nd:SVAP, btw im that customer that told them that its using a 940nm diode, they themselves didnt know lol
