Micro-heatpipe cooling of solid-state slab

摘要

A solid-state laser slab amplifier arrangement for the output of a laser beam at optimal working conditions. Pump energy is applied to a solid state lasing material so as to irradiate the solid-state lasing material and effect a laser beam with resultant waste heat output. At least one micro-heatpipe bundle which includes multiple micro-heatpipes allows waste heat to be transported away by the working medium through an approximate center of an individual micro-heatpipe from the solid-state lasing material. After condensation, liquid working medium is returned substantially by capillary action through approximate off-center areas of the individual micro-heatpipe.
