Vintage Spectra Physics Model 171 Ion Laser w/ Power cord # 0074-0101 I do not know much about lasers. I cannot test it as I don't have the key to engage power source. It came from government lab. This is the rare Krypton-Ion Powered Laser (keep Superman away). Missing screws to hold cover on. According to a data check sheet inside the laser it is: 7 Watts / 570 volts / 50 amps this is about 7-8 feet long and weights over 100 pounds. And guess what? We will ship this to you for free. We will put it on a pallet and shrink wrap this and probably send it freight. Will ship international (I get good rates - email for an estimate) please ask questions. Please look at pictures.
