Hi,
Sam and I have several high powered polarized Helium Neon lasers to offer for home experimenters and holography. These are used JDS 1145P heads with new old stock Melles Griot lab power supplies. The lasers output 17-19 mW with a good tight TEM 00 beam. The heads are 25" long. We are asking $500 plus shipping. Price a 17 mW Melles Griot 25-LHP-925 and see how much these things are new; just a power supply is way more than the whole system from us. The lasers and supplies are in excellent condition. Phil, (813) 974-2378 or pbergero@usf<dot>edu
