Amplifier with rod laser components, has active and passive optical components fixed directly to carrier via planar undersides

摘要

A solid-state or semiconductor devices are used as active components. At least one of the optical components (10,20,30,40,11,31) includes a planar underside to ensure effective cooling. The undersides of the components are fixed directly to a carrier (1). Alternatively, at least one optical component is mounted on a heat sink, and the heat sink fixed to the carrier.
