Modelocked and Q-switched solid-state lasers using semiconductor saturable absorbers

Abstract

Semiconductor saturable absorbers offer a distinct range of parameters not available with other approaches. We use different designs of semiconductor saturable absorber mirrors (SESAMs) to achieve many of the desired properties. With a SESAM, we benefit from both material and device parameters that determine the performance of the saturable absorber. Basically we are designing optoelectronic devices for ultrafast laser systems. We believe that there are many advantages to be gained using these devices, such as reliable self-starting operation.
