Yikes, since it's 445nm I'm guessing that glass cover was providing a hermetic seal? If so and they're now open, that array is going to degrade FAST. Sorry to hear that..

So I'm guessing that this has shown that the diodes themselves are mounted at angles to one another, not parallel, making it impossible to remedy for a bad array?

Be aware that if you decan it it will die quickly when run. Blue diodes die when run exposed to air. There's a company that sells modified gball diodes that were canned in an inert environment, they may be willing to recan it for you for a reasonable price so you don't destroy it. They sell...

What's up with this dude? He comes right out being a dick to Paul out of nowhere and without reason then ends it like he's all out of patience and butthurt, while still managing to be a dick to Paul. He's like a 3rd grader that starts a fight with some kid he's picking on then runs to the...

Don't take my word for it.... https://www.photonlexicon.com/forums/showthread.php/26594-Sharp-700mW-638-Diode-Quick-Test "I tested it against a P73 diode. At first I got really excited because the spot was just a bit over half the size of the P73! However, the aperture size is much larger."...

You can get a really nice, tight beam from some of those DVD burners. Look for a LPC-826 or an LPC-840 (or any open can diode, looks like a P73 mits) and with a decent lens the spot looks extremely bright when driven at 350mA.. heck, even the 3.8mm open can diodes out of laptop DVD burners can...

Dude, he asked a simple question. Which high power red diode has the best divergence? It's the Sharp, by a factor of nearly two, for a given lens. What's your deal?

Actually Oclaro specifies half intensity angle. FWHM means Full Width Half Maximum, the same as the Mits, the same as the Sharp. I don't know what you're going on about.

Aren't all diodes spec'd at half intensity angle? Regardless, if you put a Sharp and a Mits side by side with the same lens, you will find that the Sharp linewidth has half the divergence of the Mits.

For high power 638nm diodes, the Sharp 700mw unit is the best there is. For a given lens it has similar divergence to an M140, M462, NDB 7675 or NDB 7875. I used mine through a G7 lens and it was totally decent, still (as always) would be better through a single axis cylinder pair to correct...

If you had 2 PBS cubes you could combine all 3 beams in to one by using bounce mirrors to make two 90 degree intersections, one after the other, and each of the two beams to be combined would need their own wave rotator.. but still would be neat to have a single, overlapped 5 watt beam. I think...

There was something that I remembered about these diodes, that for the FAC to be able to do it's job you must use a long FL lens (like, really long, enough that it will need to be larger than what will fit on a 12mm module) to allow the beam to expand enough that the profile is square when it...

I'm curious how pulsed operation relates to perceived brightness. Does running a diode pulsed at 4 watts, 50% duty cycle appear to be brighter than the same diode running 2 watts CW? It would make sense to me that lower repetition rates for a given duty cycle would appear brighter than high...

Someone has 10 RGB modules up for sale that have OPSL greens, no output power specified but they look nice.. especially for $55 OBO https://www.ebay.com/itm/White-Light-Laser-Engine-RGB-Holography-W-Green-OPSL/233772872439?hash=item366df2f2f7:g:ARcAAOSwa3FcEn9i

Hey this is probably too off topic, and if so please just let me know and I'll delete this post and put it up somewhere else.. but does anyone remember those pictures of the crystals DTR posted about the time these lasers were coming out, which showed a crystal being pumped by a 445 pump diode...

Hey are these from LaserTree or whatever it was, the company that was selling the FAC'd diodes? I'm curious how those backfilled/capped diodes hold up, I think I want to replace an N465 with a new capped '07

I still use Windows 7 on my dual boot systems or when I need to run Windows on a particular machine and still recommend running 7 to anyone who has no particular need to run 10 (DX 12 being the only reason I can fathom). They deliberately crippled 7 so it wouldn't run on current hardware then...

Well that's disappointing. Also, I was just kidding about the cocaine thing. I don't really think that's how he paid for the laser, that would be a.. strange accusation to make given that I have no reason or evidence to believe so, much less feel the need to call someone out like that even if...

Currently using Mint 20 on main and trying out Zorin on a laptop..

I was looking for some reviews of (Polish) OPT Lasers 4 watt RGB module ( https://optlasers.com/rgb-modules/4w-mini-rgb-laser-module-with-75v-psu ) when I came across this unit in a search, which is apparently made by the other (China) OPT Lasers (seriously, is it that hard to find a unique...
