white beam with NO dichros?

[mixedgas]

Andreas, I have a bit better optics setup then simple knife edging. Plus there is a technique to get the color uniform. There are less then obvious tricks for getting this right with RGB.

Hi Steve,

at the end it's all about playing games in phase space. I really would like to learn your tricks but I have currently no commercial need so I cannot pay or sign something. I work in a diode laser company and it is a big part of my job to get ugly diode laser beams into tiny fibers. But it's all single color in the IR. Really would like to do stuff in the visible.

Best,
Andreas

This is interesting. If the the process can be applied to multiple diodes at a cost that is within the same range as the diode/driver/optical set up and produce a result that superior to simple knife edging then this would be worth pursuing. I'm distinguishing from the cost of the intellectual value ie. mixedgas's concept and implementation. This depends a lot on the process. If it is robust and can be applied to several multiple diode beams of relatively low quality, mix diverse sources ie. DPSS with an ion with a quad 445nm module or be conveniently upgradable to N sources then compared to the investment on even a modest projector I'll bet there are a number of members that would support this. I am aware that this forum is not for dummies and after few clues ... well there you go. So without expanding on the methodology can you elaborate more on the benefits? How would the output compare. Is it scalable to large systems or to a new class of beam parameters? Have you constructed a proof of the concept.
