Abstract

This paper investigates several methods for substrate removal and sample mounting. In comparing mounting methods and processing techniques, it is found that indium solder used in conjunction with substrate removal is effective for heat extraction from VECSELs material. Future use of CVD diamond should improve heat transfer due to its superior thermal conductivity.
