Abstract

Optically pumped semiconductor (OPS) vertical external cavity surface emitting lasers (VECSELs) have a number of advantages over conventional semiconductor diode lasers. High power CW operation of the OPS-VECSELs requires proper thermal design of the structure and efficient heat extraction from the active region. To achieve this goal the epitaxial structure should be as close as possible to the heat sink. Furthermore, mechanical strain caused by the mounting method should be avoided. This paper outlines several methods for substrate removal and sample mounting.
