Abstract

The use of a thermal nonlinearity for phase conjugation (PC) has been demonstrated for wavelengths from 0.25 to 10.6 μm.1−3 The advantages of the thermal nonlinearity are that it is universal in wavelength, it has a strong nonlinearity, it tolerates wide-bandwidth pulses (several cm−1), and its parameters can be chosen so that pulse durations from nanoseconds to milliseconds (or cw) can be used. The disadvantage of the thermal nonlinearity is that a considerable fraction (10% or more) of the optical power must be dissipated in the absorbing medium.
