Abstract :
We report on the characteristic parameters of two types of saturable absorber mirrors: type 1 absorbers contain InGaAs quantum wells whereas absorbers of type 2 have InGaAsN quantum wells. For both types the structure is similar. Both types of absorbers were post-growth annealed in order to characterize the stability under elevated temperatures. We investigated the static and the dynamic reflectivity of the two absorber types in the cases of no post-growth annealing and annealing at 450° C, 650° C, and 700° C, respectively. The absorbers are designed for usage in a sub-ps mode locked Yb:YAG laser at a wavelength of 1030 nm.
