ABSTRACT:
A flow channel for a fluid laser medium which promotes high pulse rate high power lasing of the medium. The flow channel operates to permit this high efficiency operation by preparing the flowing laser material to stream past a set of windows for the application of transverse pumping radiation with a very smooth laminar flow having thin laminar boundary layers. This flow characteristic is provided by a carefully configured input channel. In addition, high quality flow characteristics are further insured by an exhaust channel which triggers a turbulent flow directly downstream of the windows and provides a controlled expansion without separation of the flowing laser material into an outlet conduit.
