Alright, I do not mean to be spoon fed info. Ive been looking hard but I cant find the info I need. I am curious of what I would need for this project. I know I need a PBS cube but I am not exactly sure of what kind I would need. Also it here any other optics needed besides the PBS. I am also curious if there is practical way to focus the combined beams like you would normally with 3 element lens or g2 lens?
