Full Diode 3W RGB in progress

[epyn]

A year ago i have sold all my laser stuff. Nowadays i started to feel regret.
I'm still addicted to DIY and in lasers.
I've start a new project : three mini 3W RGB lasers.
The cases are almost done.
Their dimensions are (H) 165 x (W) 225 x (D) 190 mm
I'd like to use PT-30k galvos.
All diode system with 1-1-1 Watt of RGB (multimode diodes 462nm blue 2 x P73 red and NDG7475 greenie all lens correction and spatial filter)

I don't have all the things yet but the FB3 is on the way to me from rMuD.
I'm planning to use two FB3s
Here is my progress:



More to come as i get some component

update
FB3-SE has been arrived (thank you rMuD ! ) as well the PT-30k and i bought lot of component.
Laser related things are still missing.

nice keep us in the loop looks good

I am thinking you will have difficulties with using the same lens to correct red and blue, in my experience it has been a different spacing.

difficulties with using the same lens to correct red and blue

My old R/B compact module had use that setup and the there was no difficulties with that. The combining dichro was glued after perfect align of overlapping the beams.
As I remember the divergence was not so much bad with 3 layers DTR collimators (<1.2-1.5mRad equals to the CNI DPSS green)
It's about cost -, space effectiveness you know

If you want to share correction optics, you should consider correcting blue&green, afterwards (or starting with red) add red with its own correction. Green n blue share similar specs... reds are really another beast. The goal is to achieve similar divergence for them all.

I'm thinking about that thanks for the idea!

you're welcome!
good luck and pay attention for chromatic green-blue aberrations those cyls are not Achromatic lens
