Selective excitation of CARS by adaptive pulse shaping based on genetic algorithm

The schematic diagram for experimental set-up (BS, beam-splitter; VD, variable delay line); Inset 1 is the schematic diagram for the CARS process; Inset 2 is the schematic diagram of 4 f pulse shaper composed of two grating (G1 and G2), spatial light modulator (SLM) and two con-focal concave mirrors (M1 and M2).
