I've seen two ads for cheap ($60) laser kits in this month's Radio Electronics magazine... these are for a .5mw HeNe laser tube and power supply (you provide 12-18Vdc and an enclosure, power switch, etc. Are these junk? It seems like he perfect birthday gift for a friend who's an Optics major, but I want it to work okay (i.e. produce a coherent beam at least half the time). Anyone have any experience wih these cheap lasers? Recommendations? E-mail replies ASAP, please (her birthday approacheth) Thanks, Frank franko@juliet.caltech.edu
