1.4W 462nm Laser Diode

[Carl B]

My two diodes landed this week but I'm not going to get to try them out until I get over to Rob's (stanwax) place and that won't be until I get my two sets of 506 scanners from Bill at Pangolin but thanks to DTR for being able to supply these diodes and for the great shipping service.

If somebody from the EU is interested in these diodes, pm me.

This is the best picture I could get of the diode. This is against a same power rated 445. 445 on left and 462 on right. The 445 is putting out 1.42watt and the 462 is putting out 1.46watt.

^ Nice pic. That's a pretty accurate photo similar to what I saw too, but mine wasn't quite as dramatic a difference. You must have gotten a 470~ish one

That is a very impressive comparison.
If mine hit 460-465nm at 1.4W I will be very happy.

Ok, I finally got a comparison pic, although not a great one, the difference in color is very apparent. As evident, these are uncorrected beams.
This diode is outputting >1.3W @ 1.23A. I haven't approached the goal of 1.6 Amps yet.

What is everybody using to correct these and 445 diodes these days? The last correction I did for 445 was a prizm pair. Anybody got anything better- cyl lenses maybe?

--edit-- Nevermind, I just answered my own question. I found a cyl pair from a group buy a while back and they seem to work very well with very low losses ..

--edit II--
.. found an Osram 450 1.6W that I thought might be a good candidate for combining w/ the 462 .. but .. looking at those colors again .. hmmm .. maybe just have to bite the bullet again and combine 2 462s ..

Steve,
That last image is remarkable. That seems like a lot more than 17nm redder. The 462 looks cyan. Is the difference that significant in person? If so, I think combining this with a 445 would be a good idea. I would think that you'll have difficulty producing any deep blues with the 462 diode alone.

I don't think it's quite cyan .. 488 from the argon looks almost green in comparison .. but still a nice change from 445

I'm not far off firing up my combined 445/462 modules, so I can give you a subjective opinion then.
