ABSTRACT:
Optical breakdown in a transparent, non-linear medium used for optical phase conjugation or the like is induced by interaction with the medium of a strong laser beam propagating therethrough, resulting from electron avalanche breakdown and plasma formation. Application of an electrical potential to electrodes disposed across the laser focal volume in the medium causes optically and/or electrically ionized impurities to be removed from the non-linear medium and attached to the electrodes, thereby purifying the medium and raising the optical breakdown threshold. The threshold may be further raised by adjusting the electric potential to a magnitude at which free electrons are removed from the laser focal volume either during an optical pulse or before the arrival of subsequent pulses.
