Hi, I have been a member around here since 2013 when I looked at building a laser projector, however I decided to focus on the Boominator project first (http://forum.speakerplans.com/boomin...opic86687.html). Its now complete and I want to move back to the laser, I owned a couple of basic lasers 15-20 years ago, 1m long gas tube type thing with very basic motors as galvos, swirl patterns only. I also use measurement lasers at work so am aware of the dangers etc.
I now want to build a proper one now for Beams and Graphics and after spending the last few weeks on here I want to run the concept below past you, the experts. I have also noticed some familiar names on here from speakerplans, so hello.
I don’t have any professional purpose for the laser, just something to build and learn about as a hobby, although I will use it once or twice a year in a suitable 100-150 people venue for birthday parties etc.
1st step is to get the laser diodes and housings (DTR), I will then measure the beams, design the optics and check they work as needed. Once I have the layout done and beams looking good I will design the optical table etc.
Couple worries I have (you may have a lot more!):
I seem to have a lot of Blue, I based it on http://lsrtools.1apps.com/relativebr...nm1=520&mw1=80 for DOT and BEAM, but does 4W of blue seem about right for 1.4W red and 0.7W Green? The 4W is for the Dot, I assume this is graphics?
Diodes (all with G2 lenses from DTR)
Oclaro HL63193MG 638nm Red * 2
NDG700 520nm Green * 1
M462 462nm Blue * 2
Basic layout at the moment with what I have learned so far from here:

Thanks,
Dupe...
PS. As I did for my Boominator I will keep the thread updated.
