If you remove those to external the cube could be 2". Now we get to the point where the db25 is the limiting factor!
I forgot, is that something you can by as a module or did you build it up? I had thought of doing that twice and combining the output of the two single mode setups to get some more power. My issue was I used a 120mw green and just could not get enough red to balance or was it enough green I forget. By doubling up I can dial back the others and not loose the very nice brightness level I have for the living room. At those sizes you can go vertical and stack two and cube two like a quad but in rgb. Nightmare to align I get but tiny and quality and power.
Other thought was to go the other way and load in power and just make it for beams or have both inside and just flip a mirror to select what I want quality or power.
Interesting ideas! This sled was built by OptLasers and the optics all arrived glued in place. I have yet to hook it up to see how they did. The smallest one I've made to date is my two-in-one build which is 22cm x 22cm x 5.5cm.
Using sleds like these, I could get it even smaller. Regarding the space of galvos/amps/PSUs/drivers, I've found that the Compact 506's with the X-Laser +12V amp work out really well when it comes to space minimization.
I'm surprised to hear you say that you were having problems getting a good white on the single (or near) single mode diodes. 100mW 515NM Nicha diode (or the 120mw 520mw Osram PL520B) along side the Osram PLT5 450B 450nm and the Oclaro HL63603TG 638nm works out to a nice white for me. I tend to double them all up for 1.1W of single mode tight beams that can do double duty as graphics or beams in a small space.
