A heat exchanger is provided for transferring heat to a working fluid. The heat exchanger comprises a housing having a plurality of grooves formed in a surface of the housing. The grooves have a first end and a second end, and define fluid flow channels. Each channel has a fluid flow inlet and a fluid flow outlet. The fluid flow inlets of an alternating first set of channels are adjacent to the first end of the grooves, and the fluid flow inlets of a second set of alternating channels are adjacent to the second end of the grooves. The first set of channels and the second set of channels are arranged such that fluid in immediately adjacent channels flows in opposite directions.

Microchannel heat exchanger

A solid state laser system having at least one gas injector is disclosed. The gas injector may be configured to so as cause gas flow in a path of the laser beam in order to mitigate distortion of the laser beam due to optical path difference. Each gas injector may be configured so as to cause gas flow proximate at least one optical surface of a solid state gain element of the laser beam system. In this manner gain uniformity may be enhanced so as to facilitate use of the laser system in a variety of military and commercial applications.
