I have been looking at colour mixing, to my mind you could mix a few % 532 with 660 for a brighter red.
Has anyone tried this? Am I barking up the wrong tree?

This space for rent.
Adding a TINY bit of 532 does make the beam more orange, but you'll have fun trying to make a DPSS green modulate consistently, reliably and at a repeatable level just above threshold.

someone correct me if I am wrong but i don't think you can gain brightness by adding different wavelengths.
they are on about percieved colour not brightness
but a small amount brightness does come with mixing
works fine with bluray why not red
but if your lasers can cope with the mixing is a different question
When God said “Let there be light” he surely must have meant perfectly coherent light.
I don't think its possible to make any hue of red brighter than the original 660nm by adding any amount of green. I think adding enough green to change the perceived brightness would put you in the orange or yellow range.
Considering you need about 4 mW of 532 nm for every watt of 660 nm to get pseudo-640, the gain in brightness will be marginal. The luminance will be increased by around 5%, but the increase in apparent brightness should be less than that. Partly due to a negative deviation encountered when mixing colors on the red-green line.
No, I'm afraid the real 640 nm light is far superior, with about 3 times the luminance of 660 nm.
or you could just mix it with 640nm instead
