Good for you, rhd DTR is the source still. Can't wait to see what's up your sleeve!

Hey,
Thanks all for the kind words
I just found a 9mm 445 sitting in a drawer. It must have been from that very first group-buy projector DTR did when the projector first hit the market. Is that the same as the 9mm diodes being used to hit 3.5W? Or should I grab a fresh diode now?
I'm just realizing that I have a ton of laser gear that I should pass along to some other people.
It is probably the same as the new ones. Keep in mind a 3.5W capable diode is very rare. I don't bin them so I can't vouch for the ratio but Rick Trent who does for his kits said it is about one diode in every projector of 24 diodes that can hit that high and to do so you have to drive it really hard. He is driving them @ 2.56A to get there and most still only hit 3W. It is suggested for best life to stick 2.3A and under. @ 2.3A the average ratio is 2.6W-3.1W.:beer:
Hey DTR. It's good to hear from you.
I see - I was under the impression that it was a lot more common. Is anyone doing wavelength binning these days? If so, is there still an inverse relationship between efficiency and wavelength?
What's the best buck out there for 3x lithium voltage input, and a 2.3A output? It looks like you're redirecting the X-Drive link to CajunLasers, but he's out of stock. I couldn't find anything, in stock, on your site that would buck to 2.3A. I had a magic-enabled buck of my own towards the end of my rabid involvement in the hobby I never did anything with it publicly. If I can find the PCBs, I might just reflow one up for my project - but I wouldn't mind buying pre-built if there's something good out there.

Hi 94Z,
The M and A 140' diode are run at anywhere from 1A to 1.8A . A140's at 1.8A will do around 1900mW to were the M140's will do 2+W's . They are both 5.6mm diodes to where the NDB7875 is a 9mm diode and ran at 2.4A's . And yes the A140 and M140 will be ok in a 501b host with a duty cycle of 60 on and 30 off with 2-18350 batteries AW or Efest cells ..
