    The Laser Projectors Diode List

    Okay, got the NEC NP-605UL apart. It's a NUBM34 array. Just what I was hoping for. Not bad for a little over $100 shipped!

    The Laser Projectors Diode List

    I received the NEC NP-605UL today. I haven't finished taking everything apart yet (man ,there's a lot of screws !) but, from what I can see so far I suspect it's using a integrated array vs g-ball blocks. I will keep you guys posted. Thanks again!

    The Laser Projectors Diode List

    Hey, I just want to thank you for your projector list. Helped me out tremendously. So far I've scored a NEC- NP-P502Wl with four nubm05 arrays and a Sony vpl-FWZ60 with nubm46-71 array blocks. I think the reason so many sonys are available for parts compared to others is they glued the phosphor...

    Reference Guide: How to Combine Lasers

    Posted in wrong spot! I apologize.. please delete if possible moderator.
  5. barthchris

    I found a laser on YouTube that can ignite cardboard boxes from 300 meters away? And it's only 140 watts?

    Man that beam combiner looks awesome. I can imagine it's extremely expensive though

    PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please sub

    I bought one of those osram red modules I posted above. I offered $135 and the seller accepted. If the seller happens to be a member here or lurks I apologize for posting the price but look at it this way, perhaps it would help you sell more modules. Changing subjects, I found another deal...

    PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please sub

    Took a few years off and got bit by the laser bug again. I just snatched a great deal on eBay for one of those adjustable 10 to 100 volt 0-10A boost modules that was listed as a laser driver for Numb34. It included a 24 diode 445nm 60-80W osram module. I don't think the guy knew what he was...

    New Colossal UV Laser Diode - Nuvoton KLC432FL01WW - 3.3W 405nm and Beyond!

    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...

    Incredibly powerful single-mode semiconductor lasers on the horizon

    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...

    New Colossal UV Laser Diode - Nuvoton KLC432FL01WW - 3.3W 405nm and Beyond!

    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??

    FDA compliance for manufacturers, some insight is needed

    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

    New! Sharp Diodes 1W 520nm & 5W 455nm & +2W 638nm

    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...

    100W Blue Laser Exploding/Vaporizing Black Coffee.. (Video)

    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...

    a few new pics

    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...

    POLL - Close the politics thread?

    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...

    Great reading on laser diodes

    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...

    Sale thread/ Hosts/Heat Sinks/Focus adapters/lasers

    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
