Abstract

The potential for serious component damage in a laser system due to reflected pulses increases rapidly with output energy. Optical materials for interstage isolators are not available for large 10.6 micron laser sytems. We show that an excellent passive protection technique can be realized using optically induced gas breakdown in the high pressure laser medium. The reflected energy flux is reduced below the component damage threshold by using spatial overlap to increase the strength of the breakdown.
