Compact externally heated discharge tube for metal vapor lasers
Abstract
A compact externally heated discharge tube of 25-mm internal diameter is described. The oven made of alumina tube, tungsten heater, and graphite felt insulation, takes about 45 min at 1.5-kW heater input power to reach temperatures in excess of 1500 °C. Its use with a copper vapor laser is demonstrated. The laser gives output power of 500 mW at 500-Hz repetition rate.
