combing 405nm

[andy_con]

BTW, slightly side-stepping the topic, but:

Is it possible to get a quad kit, and knife-edge two 405nm with two 660nm beams together, saving up on a dichro?

using the right optics it shouldnt be problem

ive searched for this but have not found a answer for it.
but is there a cheap way to combine 405nm beams?
i want to get atleast 500mW of 405nm. i have a few diodes that get to 150-170mW so is there anything to combine 4 of these?

The word CHEAP is not in the laser dictionary....

these lenses with the blue AR coating are perfect for 405-450nm
