Compact systems cool solid-state and gas lasers

The design of a high-performance laser-cooling system requires careful integration of a number of components. The type of laser and its end use will determine the relative importance of individual system attributes. A Nd:YAG laser, for example, will require that no cooper be used in the deionized-water circuit. A laser used in a doctor's office will need to have lower fan and pump noise than one used on a factory floor. The optimum cooling system for a particular application will be the result of a number of iterations and compromises that satisfy the heat-transfer requirements and maintain the needs of both laser manufacturer and end user. This article addresses the cooling needs of both solid-state and gas lasers from the viewpoint of the laser supplier and the end user.
