The aim of the present study is to demonstrate the influence of the spatial nonhomogeneity of the laser beam intensity profile on laser induced breakdown in aqueous medium with the use of optodynamic methods. In the experiment the optodynamic waves were induced with pulsed Nd:YAG laser beam which had several"hot spots". The resulting optodynamic transient waves were detected with two detectors: a laser beam deflection probe inside the liquid, parallel to the liquid surface and a piezoelectric transducer at the bottom of the container. The results of the experiment indicate the existence of numerous smaller waves that are observed before the main signal in the optodynamic wave form, contrary to wave forms generated with a laser beam having a smooth spatial profile.
