Just about everyone has heard of or visited Sam's Laser FAQ but few people realize that one of Sam Goldwasser's keen interests is stabilized Helium neon lasers; for these he has become a leading authority. For use with interferometers and for scientific experiments requiring long coherence length these are great. Output power ranges from about 0.5 mW to 2 mW and these are single longitudinal mode by design. We have many lasers ready to ship...Spectra Physics 117 and 117A, Coherent 200, Melles Griot STP 910 etc. Prices range from $1K to $2.5K and we offer money back if not satisfied warranty. We have sold lasers to NIST with no issues; sam adjusts each laser prior to shipping for optimal performance. Phil Bergeron, 142laser, pbergero@usf<dot>edu, (813) 974-2378
