Hybrid SESAM Output Coupler

Case ID:

A novel hybrid semiconductor saturable absorber mirror (SESAM)/dielectric output coupler has been developed and employed to demonstrate a mode locked vertical-external-cavity surface-emitting lasers (VECSEL). The hybrid SESAM enables a greatly simplified optical layout for developing short pulse laser sources utilizing semiconductor based VECSELs. 

Because the hybrid SESAM acts as both the saturable absorber needed to mode lock the laser, and optical cavity output coupler, one can make simple linear optical cavities that support high repetition rates and greater cavity stability. This could be an enabling technology for VECSEL-based frequency combs. The hybrid SESAM can enable development of novel laser systems or as a stand-alone device that could be used as a component in laser systems.
