Mitsubishi ML520G71...Red Holy Grail or Flashlight Fail ??

So what Kind of power are you seeing out of this diode? I only fired up one of mine, but it was holding at 730mw at under a amp of current. This was metered close as I was loosing alot to the wing issue I have, but reading there can be a big difference? some people peak at 500mw?

I measured 550mW after collimation and correction optics, not tested directly from the diode yet but will and I didnt crank up the power too much.

Any special cooling on these? I find that on a cold plate they hold output will sustained at 600mw, but if just on a piece of aluminum 4x6 inches, the power quickly drops in half due to heat? I also have the driver mounted on it so that is also adding heat.

Also Andy you were correct it was a Lens issue, after reading about some results with the 405-g-2, I tossed a o-like blue on it and got good results.

I have some <3mm FL's on the way so hopefully they will help even more.

also made a nice yellow with 350mw of green, this red at 380mw.

Purtty Nice pool/beam table . Rack up those lasers

These are test for my buddy's first build (should end up in the 1.2~1.5w range). He also has some opnext available, we are going drop this module once I get a care package mount into my existing box and then compare it to (2)knife edged 660's with optima glass PBS's with one of the 150mw opnext. Trying to see if the tighter beam will give a brigher appearance and also compare the red shading (also the landing on the galvo's). I am in process of a build also so, been learning what these can do for part of it . Plan on PBS 2 of these reds and dichro mixing them in with my 8~12 red diode 660 build. Yes we must get going though. I want to see a 6w projector / beam rail by Christmas.

It is crazy how bright 400mw of 640 is compared to 1.7w of 660, check out the pic below. The tighter beam is the 8 660's. But the brightness is about equal if not leaning towards the more orange 640.

verry nice yellow !

do you have some animation pictures ?
or is your beam still not a good dot ?

Use used an ML G520G71?

It makes a pretty good dot, just haven't gotten to scanners yet as it is all just test platform right now.
