Hm the ones I can find have a heavy green reflex and their optical density seems about twice or thrice what you'd need for a 1W CW laser. Maybe it's unavoidable given the closeness of near IR and deep red, but I wonder if there exists glasses with a cutoff sharp enough and reduced OD so as to not result in noticeable color shift.
