Pulsed photoacoustic measurements have been carried out in liquid CS, using 532 nm radiation from A frequency doubled Nd:YAG laser. Variation of signal amplitude with laser fiuence clearly indicates the role of multiphoton processes in the generation of photoacoustic effect. It is also shown that four photon induced dissociation and live photon induced ioniZAtion are likely processes in CS, and 532 run radiation.
