Abstract

Motivated by the requirements of the gravitational wave observatory mission, a diode laser module based on resonant optical feedback from a monolithic LiNbO₃-cavity has been realized. This approach enables the diode laser to reach a phase noise level comparable to that of an NPRO. In order to allow for a compact setup, a hybrid micro-integration technology was utilized to omit any movable parts. Frequency tuning is realized thermally and electro-optically. Results of a prototype module emitting at 1064 nm will be presented. In addition to its intended purpose, this type of laser is ideally suited for coherent optical communication applications.
