An experimental study of self-induced phase conjugation in a CO2 laser
Abstract
A four-wave mixing scheme has been implemented in (S-34)F6 with a feedback loop amplifier for the microsecond pulsed emission of a CO2 laser with an energy in the reflected wave of 1.8 J at the maximum gain line. Partial compensation of model inhomogeneities in the loop resonator is demonstrated. An analysis of the spatial characteristics of the reflected wave indicates that exact phase conjugation is absent in all the known feedback configurations that have been tested in the experiments.
