Paper Abstract

High power laser diodes have found a wide range of industrial, space, medical applications, characterized by high conversion efficiency, small size, light weight and a long lifetime. In this investigation, high power 940 nm laser bars were mounted on optimized micro-channel heat sinks (MCC) using AuSn/CuW and In Soldering schemes. The optimized MCC cooler has decreased pressure drop and increased heat-sinking capability. The improvements in thermal and strain characteristics will be reported through wavelength, thermal rollover, spatial spectrum, SMILE, and polarization.
