Stationary cavities were formed in liquids by trains of laser pulses having the following characteristics: high absorption, high repetition rate, and high energy per pulse. Under these conditions laser pulses may be transmitted through several millimeters of ‘‘opaque’’ liquids by a cavitation effect. This facilitates material cutting and laser surgical operation under blood or under water by CO2 or excimer lasers. A simple model is presented to explain the cavitation effect.

    The self-focusing of a laser pulse through a tunnel ionizing gas (helium) has been studied in both non-relativistic and relativistic regimes, relaxing the near-axis approximation. In the non-relativistic regime, the laser pulse produces multiple ionization of the gas and faces strong defocusing...
