I was skeptical that star wars type laser weapons would ever be practical in my lifetime. Now Im not so sure and Im someone who is very skeptical with claims of what will be the next greatest thing. Chesk this out. It really is mindblowing. The small 1mm prototype was fed with 110A, 3mm...

I recently stumbled upon this. Great source of in depth information about these little photon amplifiers we all know and love. Created by the manufacturer of the equipment that slice/dice the semiconductor material that forms the optical cavity/gain medium https://www.tomosemi.com/wiki/

So I waited in anticipation for my 465nm diode to arrive from DTR. Pressed it into a heatsink and used a PS to test. Divergence with Gball is absolutely unacceptable so I decided to remove the can the" proper way" with a vice and pliers. Anyway I did a real bone headed move and somehow...

I have a pile of unidentified lenses. Some are for red, some blue. Optical coating reflection varies . Some clear, some have a yellowish tint when viewed at an angle, some have a red hue(obviously those are for blueish wavelengths). What gives on the clear, crap or no coating?

Long-time no see fellas! Getting back in the light amplifier hobby after some time off. I used DTRs excellent service to obtain a num44 V2 and a blackbuck 5.5A driver. I had it working but was testing with two 18650s outside a host and made the rookie mistake of connecting power in reverse...

I have not kept up with lasers for the last couple of months. I did a quick scan over the threads and did not see this discussed my apologies if so. Anyway I just stumbled upon this. Link below. Don't know if this new module is a good or bad thing for us. Im leaning towards the bad side because...
