Saturable absorber mirrors are Bragg-mirrors with AlAs/GaAs quarter-wave stacks, grown on GaAs wafers with one or more low temperature GaAs (LT-GaAs) or InGaAs films as saturable absorbers. Patented semi-resonant allows to meet the requirements of different passively mode-locked laser applications in the picosecond and femtosecond region. The saturable absorptance of the fast response films of LT-GaAs can be adjusted in a wide region.
