Shock acceleration of particles in a laser beam
Zakharov S. D., Kazaryan M. A., Korotkov N. P.
A motion of strongly absorbing particles suspended in a liquid caused by a periodic-pulse laser beam has been studied theoretically and experimentally. A mechanism of shock acceleration of particles is proposed. It differs from the mechanism of convective entrainment. This new method makes it possible to perform patterned microscopic treatment of a target surface during bombardment by a light-controlled flux of particles with velocities ~106 cm/s. © 1994 American Institute of Physics.
