Abstract

Design of novel integrated structure-semiconductor broadband saturable-absorber dispersion controlled mirrors for mid IR spectral range lasers have bene discussed. The novel design of SESAM is based on the multilayer structure like Gires- Tournios interferometer. High reflector consists of the metal mirror with low losses in this spectral range. Top section consists a few layers forming the linear grown dependence of group delay by resonance effects of interferometer. The thin HgCdTe quantum well layer with nonlinear absorption can be included in transparent semiconductor layer near the antinode of standing wave. This structure has low amounts of nonequal thickness layers that create the high reproducibility way of such type structure experimental realization. SESAM design for Cr:ZnSe laser is analyzed in detail.
