High Brightness Green Laser Pointers

If you are an optical SETI researcher and looking for a great tool for giving talks and demonstrating the efficacy of lasers over microwaves for interstellar communications, you can hardly do better than to purchase one of the new high brightness semiconductor laser pumped (frequency-doubled) laser pointers.  They will make your colleagues "green with envy" and amaze your students.
