Hi, Ive been looking all over, and through other forum posts, but nowhere is giving me the direct information i need. I want to construct a LM317 regulator circuit for my 1W 808nm laser diodes. I was particularly hoping to have the regulator fit inside the laser housing. My problem is, i dont...

hi, im an ebay seller in australia of 70mw green laser modules, actually the ONLY person in australia on ebay selling modules which arent super expensive. anyway, recently ive been having a problem, some of my buyers complain about the scatter comming off the dot, heres an image one of them sent...

hello, I recently made a bulk order for some 70mw green modules, and the seller was kind enough to add a 150mw pointer for free, though i checked and they sell it for about $18, but still im happy i got it. best of all, its strong enough to pop balloons at close range, and because of the bad...

hello, recently i bought a pack of 10 laser housings from an ebay seller named techhood, which are for TO-5 infrared laser diodes. Now, when i received them,i discovered a huge problem! These housings have an inner diameter apparently, of 10.3mm (i measured 9.9mm), my lasers, being 8.95, are...

hello, Ive been attempting to source laser modules and diodes lately for the purpose of reselling cheaply. Lately though ive noticed that many high powered laser pointers seem to cost far less than the diode of that power rating and wavelength! whats up with that? ive confirmed with a few...

hello, Recently i bought a focusable 250mW IR laser, but since it was greatly disappointing in writing on my black foam sheet, i decided to buy some 1000mW laser diodes and a collimating lens. I bid $40 on two lots of 5 1W diodes in a thoughtless impulse, thinking that $5-8each was to good to...
