    445nm diode MURDER thread

    chris (heerursciences) was the first one I read who killed a diode here.. it was over 2 watt optical output, if I remember correctly. manuel

    Announcement Regarding The Novalasers Atlantis-1

    I applaud your decision, Novalasers! and yes, I would very much like to know if this was an internal decision only, or of other, maybe large companies, are involved in this decision.. manuel

    445nm Laser Diode Compilation Thread

    Re: 445nm Casio Laser Diode Compilation Thread congrats, chris! afaik you are the first one to damage a 445nm diode! ..all future ones shall be measured against yours! :-) manuel

    445nm Lens Comparisons!

    Re: 445nm A130 Lens Comparisons! Thanks RA and Larry for posting! what exactly are you testing as cylindrical lenses? cheers, manuel

    445nm Lens Comparisons!

    Re: 445nm A130 Lens Comparisons! i just had the chance to do a few first tests on my 445nm (almost typed 405.. too used to it!) diode - thank you a lot, dave! :-) i am pretty impressed on the aixiz 3-element-lens too. the dot seemed small, at several ten meters. flying setup, so no numbers or...

    445nm laser completed

    thanks for linking, RA_pierce! hmm, actually its obvious.. with such an aspherical beam, it is expected that the beam looks totally different, depending on how you "rotate" it. and guess how they rotate it for beamshots.. still, I didnt think about this, it was just too obvious! :-) manuel

    445nm laser completed

    nice build, BB! ..and now think again about the "bright" idea to have a 500mW blu-ray pointer.. which looks as bright as a few mW green.. uhoh.. manuel

    I love chocolate

    Re: Why is 445nm a better wavelength for burning than 405nm heh you are right! I meant the same, and seemed to have confused myself.. edited. thanks for reading carefully! :-) manuel

    1W to 30W of 405-410nm from a Nichia :)

    wait wait! laserdiode or LED? where from? I will eventually get me a mid-uv "flashlight", right now it seems the 365nm nichia LEDs are the best stuff out there.. manuel

    Mitsubishi 638nm 300mW CW

    funny, almost no response.. this seems to be the brightest red (singlemode) diode available! I bet the people on photonlexikon are all over it already! :-) manuel

    Optical Trapping - Real Laser Tractor Beams

    what the hell! if I wouldnt have seen the videos, I wouldnt believe you with this! :-) tried it with 500mW bluray, 300mW red, 100mW green. glasslens with f' of about one inch. smoked paper and a pentip. with doors closed as well as under a small-melon-sized glasssphere. almost no airmovemend in...

    I love chocolate

    Re: Why is 445nm a better wavelength for burning than 405nm right, Burnsy! a single 405nm photon has more power than a single 445nm photon. but when measuring optical power, in mW, you dont "count photons", you measure the power. so 100mW of 405nm will contain _less_ photons than 100mW of 445nm...

    445nm Laser Diode Compilation Thread

    Re: 445nm Casio Laser Diode Compilation Thread thanks for the info, chris! ..what came to my mind: remember those 12x BR sleds? they have a "beam circularizer" cube right in front of the diode.. unfortunately I never got any of those, just the sled without that cube. could someone check if...

    awesome news! thank you, dave! :-) manuel

    Right now it must really be a uneasy feeling to be in your spot

    The thread about "real" goggles/glasses. . .

    I asked OEM about prescription glasses. they answered me two types, "Style 38 Lrg Adjustable Framed Fitover" and I think "Style 60". I got the 38 one, am very happy with it, since years! manuel

    affect on 473nm

    haha you are right! it was with every color I first saw.. red in the movies "predator" and "terminator", green in "alien vs predator" (..which sheds some interesting light on my childhood i guess!). now i just fire up my violet one from time to time to play around with fluorescence.. man, those...

    affect on 473nm

    funny.. so many people seem to prefer 473nm over 445nm, as well as prefer 635nm over 650nm. yes, both (635 and 473) seem brighter than their "deeper" counterparts. BUT: imagine you have a white laser. it surely would be brighter than red or blue (but not brighter than green). but you would have...

    Idea for driver/host

    running these with one li-ion is right at the border.. the AMC7135 drops 0.2 volts, the diode needs more than 4 volts (i think!) so you wont have the full runtime, at least. once the battery-voltage is too low, the diode wont draw any (useful) current at all, even though there is still much...

    445nm diode MURDER thread

    ..yes, they may "enhance" the manufacturing process to have them closer to their requirements. in case this is cheaper, anyway. the difference between the BR-diodes and the (whatwastheirname) 445nm ones is the relative power we drive them at. with the BRs, it could have been 4 times (wild guess)...
