Saturable Absorber Mirror

         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.

         With our patented semi-resonant design we 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 with our design in a wide region.

We are open for new ideas of our customers to extend our current portfolio of saturable absorber mirrors with respect to certain parameters like wavelength, low intensity absorption or relaxation time.
