WTf, 7$? it cannot be better than this which i burned lol... Good price, maybe i'll buy it. why use optical adhesive? cannot i use normal epoxy, or silicon? Anyway, i get the idea of replace DL because it can be interesting if i get a little more power using a stronger DL. Because i have...

i disassembled it. Anyway, i can get a replacement diode (200 mW) on ebay at about 4$, it's a lot more affordable that a decent green laser pointer... If there isn't too many alignment problems, i can try to reassemble the laser. As we can see on the picture, the crystal is held by a brass...

Here: [img=http://s23.postimg.org/4j2h68oo7/20150606_183151_1.jpg] Sorry for the late. Any ideas? Thx

hi, i have one of the famous chinese green laser pointers. After i played with the pot (lol) i burned the ir pumping diode. So, can it easily replaced, maybe with another one a little more powerful (not too much, i know the dpss crystals cannot withstand big optical stress) ? There are...

Unfortunatly i don't have LPM, i tried it at 400 mA, the brightness does not increase significantly at eye looking; i hoped in a better beam visibility

Thanks Man. So I think i'm already at the laser limit. I hoped a more intense beam, it looks like a common 16x dvd burner DL.

Hi guys. I get a 22x LG dvd burner: GSA-H55N. I extracted an open can laser diode. I read around which the laser diodes from a 20/22x runs on about 400 mA. So, after placing it in a optic module, i supplied it with about 400 mA and it works well. The "problem" is: beam intensity is very similar...

and what about try to pump crystal with a DL a little more powerful? i know that the crystal could be damaged with high powers, but if i oversize the DL with +50 mW could obtain bright green laser? bad idea? :D btw thanks for infos

ok i think the LD is damaged... i was not able to reach the full brightness as same as the first run... so, if i replace the LD with another 808 nm, keeping the driver? is it possible?

i red the review ( http://laserpointerforums.com/f52/mini-review-50mw-green-module-fasttech-80522-9.html ) on this forum and yes... i learn touching the pot is a bad idea. But is too late, i have played with that pot many times lol. But the behaviour is stranger, because if i play with pot/pcb...

i'm returned :D so... i have some trouble with this laser. if i turn potentiometer , the laser intensity varies with a strange behaviour; sometimes the laser is bright, and then fades and looses power. If i turn potentiometer, the beam increase brightness but then some turns the light turns...

Now i have already the full module ._. What's the right procedure to fit the diode? i'll not even use the PSU to power my laser diode... :\

i'm using a mine homemade PSU, based on 317, with a current limiting and short-circuit protection. I don't know what happened... But the light was weak also at first run at 350 mA. I cannot explain my faliture. I sticked the diode in the module with hammer... can be this the mistake? I cannot...

Holy shit. i think i burned the diode. fuck off those stupid DLs they are so weak that if i look them they die. I think my PSU has some problem... But the current was setted on 350 mA max. Why these diodes are so weak? I have a red laser from 8x dvd burner and i drive it with potentiometer...

Cannot find datasheet or specs sheet :\ Anyway, has this diode IR also? interesting.. how mani mW?

I just solder the diode. I didn't solder the "not used" terminal... it's correct?

Thanks. useful threads :) i have to build the driver. Can a standard current limiting 317 circuit do a good job? max current for this diode is 600 mA right? If i link my wrist and the solder with earth ground cable it's safe?

Hi again guys! Today has just arrived my diode. Now i have: - LPC 826 - housing with lens - heatsink i do not have the copper module... i think i'll try without it. I'm gonna to stick the diode into the standard module.. Any suggestion??? How can i proceed to minize risk of laser faliture?

Done. I bought laser diode, laser module with lens and heat sink. I think i'll build driver from myself. Any suggestion for mounting the diode? Is the copper module necessary? if i mount the heat sink on standard module will it be ok? I'll update the topic when i'll receive the items (about 1...

i bought fasttech 50 mW green laser.. i'll update the topic for my impression. Thanks all for suggestions. PS: can it be powered with one 18650 li-ion 3.7V cell, right? It should be have built-in driver
