Paper Abstract

Influence of pulse duration and focussing mode the first and second harmoics radiation Nd:YAG lasers on shock waves characteristics arising at optical breakdown near to a surface of water was investigated in the present work. The lasers with different parameters of radiation were applied to making the optical breakdwon. The first laser had pulse of duration 4 ns, energy 240 mJ, and wave length of radiation 1064 nm; the second laser had pulse of duration 18 ns, energy 400 mJ, and wave length of radiation 1064 nm; and the third laser had a uplse length 5 ns, energy 180 mJ, and wave length of radiation 532 nm. The laser pulse was focused by the lens (f=70mm) above a surface of a liquid, and then it was directed on surface and under surface of a liquid with the help of the microscrew. For each case, was carried out registration of optical breakdown and arising shock waves by the shadow camera. THe spectral complex "Flame Vision PRO System" with the time resolution about 3 ns was used to analyze the shadow images.
