I noticed that the 200mW green laser pointers on ebay are now being
joined by 200mW red laser pointers.
They describe the red ones as DPSS too. Is this true or are they just
getting mixed up? I'd have thought if they were using an IR laser to
stimulate emission of another colour then they'd have tried for 635nm to
make the beam more visible (it's 650nm). Then again the lasers might be
being manufactured for a disk storage application where 650nm is good
enough.
