Single-mode solid-state laser butt coupling pumping shape having a fiber-coupled diode

摘要

(57) [Abstract] The present invention aims to provide a laser of a single transverse-longitudinal mode operation. A simple way to provide a laser of a single transverse-longitudinal mode operation is disclosed. Fiber coupled diodes, flat - are butt coupled to the laser crystal for pumping a solid state laser in a flat resonant optical cavity. It is possible to obtain a good overlap between the laser mode and pump size. Furthermore, thermal effects in the cavity, not only to provide sufficient overlap between the laser mode and the pumping size stable resonant cavity, to increase the single-frequency performance.
