Nice "Williams Diner " you have there bud ... same era as Roadshow ..... quality pinball ..... but Theatre of Magic and Pinbot ... are still my favorites ... all went downhill with Pinball2000 .....

Well was pretty happily surprised, just tossed the scanners in front of the beam no steering mirror and a off balance cardboard shim, at it put 3.97W out the scanners. Loss of about a watt, but heck the beam even passes straight through the mirror not just missing on the edges. Thinking with some tuning I can gain another 300~500mw's

I am considering making this into just a projector as I am thrilled with spot size and the beam, just need to see how good it handles continuous scanning tests.

If that is the case I'll be another one working and death beams, trying to get 5W of blue and 5W of red onto the beam table build. The pickup a 2W green sometime way in the future as money doesn't allow right now, but could still come up with about 800mw to put on it short term. Plenty for at home when the beams are all dialed back anyhow.

Oh decisions....

Tweaked it up and ended at 4.39W off the scanners. Thinking i'll chill the P73's and M-140s down abit more and go for more power Still would love to have an honest 5W off the scanners.

Are both the P73's and M-140's in series? How much current are you running through each right now?

Yes, and I don't know. I tuned them for power, seeing where gain made no more, then backing them down and making sure it would hold power constant for an hour at 100% duty cycle.

Well the galvo finishing touch tuning after swapping to the larger mirrors went pretty well, happy how it came out, not perfect but plenty close enough for this projector. Thanks buffo for the tuning guide

Video of the first run of it. Scrub through it if you wish kinda long. 2 minutes in are some good beam shots. Finally red I can see @ 1:30

Wow, nice work John.. I've started the planning process for a RGB 1.5watt laser to go into Discoscan projector.
Will be the first all diode based laser system I own.

I have found for my home use 3/4 to 1.5W max is best. I'll be adding modulation color balance / power adjustment pots in the modulation lines on this. There is no way i'd fire it up with my daughter around at full power the scatter is pretty intense.

Now to finish up the case and some mounting. Actually liked the way the3/8 rod has worked. Hopefully it all bolts together as i have envisioned. crosses fingers.
