Ok that doesn't look so hard to make. I'll probably need to find the regulator at radio shack tomorrow, but the rest looks doable. I'll give this a try and see what kind of results I get. I will measure after the scanners and dichros and hopefully get somewhere in the rated neighborhood. Do you think there is a loose wire or something in the projector that's causing the blue to do it's craziness? Thanks for your help PB.

The regulator is a 7805. Pretty common.
I'll read back through you blue experience tonight.

OK I did the abstract generator method as you described. Definitely higher output than the other way I was measuring. My red hit around 500mw, the green hit around 500mw, but the blue only hit about 200mw. I think it might be a little out of alignment. When I look at the case when it's opened, it looks like part of the blue beam has an obstruction with a bracket. I'm going to see if I can move that. It looks like it is hitting at least half of the beam. Probably jarred during shipping. Still not hitting the power that I think it should, but it's getting better. I will try the ILDA plug that you mentioned above, PB, and see what I get. Also, I will tinker with LSX and QS to see if the software makes any difference. Thanks for your help guys.

meter the beam at the aperture of each laser module. The dichros and scanners will impact your reading.
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.

I don't think I can get the LPM between the aperture and the dichros, except for the red laser. The others are too close I think, but I'll give it a try.

be aware that in *many* cases the advertised output power of a projector is just the sum of all the laser modules at full power. it's not the power at the projector aperture, or the power for a balanced white. cheap dichros and mirrors can also loose a surprising amount of power.

What brand of laser is it out of interest?

White-Light - they are Sollinger laser modules.
Here's where I'm at now. The red is producing about 800 or so mw. The green is getting about 1.2W after going through optics. The blue is hitting about 1W going through all dichros. Unfortunately, I can't get in front of the laser aperture because they are too close to the dichros. The red and green modules shoot straight out into the dichros, etc. The 473nm has some string box right next to the dichros that has mirrors inside it. Where the laser comes into it, it says "Input" and it exits the box labelel "Output". It has an adjustment on it that moves the mirrors up or down. This has a significant impact on the power. If I move it around some, I get anywhere from 200mw to over 1W. What is it? My guess is it's to help with adjustment or alignment, but I can't really tell. On the case, it's labeled "Blue Mod Adj".
Anyway, it's getting closer and I feel better about this now. I'm still not hitting the rated power of 5W, but I'm getting much closer. I know my optics are dirty so I'm going to get some canned air and see what it's at.

Okay the input/output module is a PCAOM to modulate the blue laser.

Please take pics, I got to see whats going on.
