Kuehleinrichtung fuer Gase, insbesondere fuer Lasermedium in einem Entladungsraum

The cooling arrangement includes at least one hollow body which contains a gas, whereby the surface area (5, 7) of the hollow body (1) facing the gas (4) is at least partially, preferably completely, overcast with a coating (6) which has a high heat conductivity and an, at least nearly, electrically isolating characteristic. The coating consists preferably of diamond or is composed of a similar material. The hollow body is composed of quartz glass. USE - Especially for laser medium in discharge room. ADVANTAGE - Enables optimal cooling of gas without risking its contamination.
