A Nonlinear Artificial Saturable Absorber

Caption

A nonlinear artificial saturable absorber works as follows. The plane of polarization of low intensity light beam does not change in the absorber and the output polarizer blocks the light (images at the bottom). At a high enough intensity, typical for femtosecond pulses, the plane rotates 90 degrees and the light pulse passes through the polarizer.
