I have seen a lot of green lasers with higher power that are not running with an IR filter whose beam profile has a yellow/green center. Anyone else seen this? I have a theory about this and wondered what you think? I have seen some IR beams that featured a dim red coloratiion. Green DPSS is powered with IR as everone knows. Unfiltered greens have a substantial amout of multiline IR/green in the makeup of their output correct? See where I'm going with this? To create a yellow laser on purpose, as in the way Rog does it green+red=yellow in the correct proportions. Therefore it is my humble opinion that their is likely to be some yellow in the combined IR and green output. It seems to show up in the center of a powerful green. Thoughts?
