Hello, a simple question. If i measure the laser beam of a diode that absorbs 100mW current, what value should i read. I mean, i suppose there is some power loss between current absorption and light emission, isn's so? Thanks!!

Hello, I've two laser diode possibly broken. All laser is tested in a close box using a webcam (a.k.a. eye security :) ). One is a IR from a CD-RW, it absorbs current from 10mW to 15omW, but emit low light, as comparison i've other IR from CD-RW, up to 30mW laser beam begin to blind the webcam...

Hello, i'm building a laser engraver, using a 150mW red diode. The laser it is mount on an AixiZ 5.6mm housing. I'm wondering this: does a 5 to 30cm distance from the laser to the engraving working plane affects the engraving capabilities of that laser? In other words, fiven a 150mW power...

Hello, I would like to know if there is a low-cost semi-transparent laser protection sheet to use as a window for a chamber of a laser engraving machine i'm building. Actually i'm using safety glasses, buy maybe i can build a safety box, like the pro laser cutter has. My laser engraver has a...

Hello, I've read a few post about watching the laser dot, but i can not find the answer to my question. I'm building an engraving machine, using a DVD-rom writer red laser. I suppose it's a 100/150mW laser almost. Laser it is mounted on a 12x30mm 5.6mm TO-18 AixiZ housing. Question is: is it...

Hello, i'm would like to build an engraving laser machine using two old cdrom. The laser i would like to use comes from a DVR burner, it should be almost 200mW, red laser Before connecting the laser, i would like to ask you a suggestion for goggles. Here some link: ~30Euro: Protection Safety...
