Paper Abstract

The design and development of a compact, low cost, subsonic cw HF chemical laser with expected output power of the order of approximately 100 mWatts that requires less than 5 lt/s pumping capacity is presented. A theoretical estimation of the minimum pumping capacity required in order to obtain an output power of 100 mWatts is given. The laser operates with a He/SF6/H2/O2 gas mixture at an overall pressure of 4 - 8 mbar. A dc electric discharge is used for the SF6 dissociation. In order to operate at such low gas flow rates the mixing channel dimensions were reduced down to a cross section of 0.2 cm height by 13 cm width. Hydrogen is transversely injected into the flow through approximately 285 holes of 0.03 cm diameter. This low cost compact laser system is suitable for a wide range of experimental requiring mid-infrared cw laser radiation such as laser-tissue interactions and environmental studies.
