My preference for far field has been the 2E lens but you just convinced me to get with the times and buy several G8 lenses...

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...

Gotcha. I wonder if pumping is the reason this diode exists. Certainly, there can't be much of a market for BR writers. I spied this diode on Aliexp a while back. Got excited and then looked at the price. Lol! Even though it's a multimode I would love to have multi watt 405. I love...

Wow!!!! I'm assuming this is a multimode diode??

Yeah, posted on my phone, could tell something went wrong but didnt have time to fix.. Basically was commenting about the amazing pics from the OP (bruce).

The answer is no. Lasers are uniquely hazardous in that light properties can focus down to a very small, intense spot easily burning the retina. Sure, a broadband source of light (almost anything not a laser) can do this if its bright enough(nuke bomb bright) but it's highly unlikely

I bought some of these from Techhood. https://www.ebay.com/itm/264557183792 The package was smashed during transit but I was able to salvage one diode even though the output window was smashed and pins were pressed so hard they almost cold welded to the diode casing. (Ringo?) did...

I'm trying to figure out if you're pausing between because you aiming, letting the laser cool a little or if your eyes are screaming in pain! Recently I was so close to pulling the trigger and making the same basic thing you have made. Even though they are an incredible watt per $ price...

Wow just wow!!!! Those pics are incredible. Are the mirrors all FS mirrors? Even the large ones on the base? If not just find some old CRT projection TVs giveaways on craigslist or if you are lucky enough to be able to raid the electronics recycling container at your local landfill/collection...

I’ve been here quite some time. Not a super active poster because I have too many hobbies but I do read a lot here. Never once have I ventured into the political thread. I doubt new users will venture over there but maybe so. I’ve thought about people getting offended. It’s my opinion that...

Yes, it is. For me it didn’t dive too far into the weeds that the information was overwhelming but it also wasn’t simplified to the point of losing interest. Failure mechanisms was my favorite part. I betting that anyone who has been around here for a while has a whole pile of dead diodes...

Wow! received some of Rich’s beautiful creations. Shipping was close to light speed. Everything was meticulous and meticulously packed. Even little touches like heat shrink and the Allen key for set screws. Well done Rich! Seriously, I’m just blow away! Chris

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/

GTFO of here with your negative, condescending attitude. What contribution are you making other than making yourself look like an ass? Seriously, if you talked like that to someone in real life you would eventually get your ass beat. Probably not even a EE lol! Even if you were you...

Some people haven’t learned social skills yet. Seems to be a common thing among “ laser nerds” lol! I’ve been here quite some time, I’ve noticed some can be really confrontational. Yea, it all boils down to insecurity or some other weird incel type shit I seriously doubt they would ever...

I Add this to my last order!!

How much
