Abstract

The low-temperature cavitational disruption by trains of laser pulses was demonstrated in water. The trains used in the experiment were generated by a Raman laser at a wavelength of 1626nm. The mean value of the fragmentation threshold energy density per pulse in a train was estimated to be equal to 7.2×106J/m3. The corresponding amplitude of the negative pressure had the order of 67bars at a temperature jump of only about 2°C. This result opens up prospects for developing precision nonthermal cavitational laser surgery.
