Abstract
Pulsed photoacoustic measurements have been carried out in liquid CS2 using 532 nm radiation from a frequency doubled Nd:YAG laser. Variatio n of signal amplitude with laser fluence clearly indicates the role of multiphoton processes in the generation of photoacoustic effect. It i s also shown that four photon induced dissociation and five photon ind uced ionization are likely processes in CS2 and 532 nm radiation.
