Optical phase conjugation in laser dyes

The nonlinear optical response of four laser-active dyes (Pyridine 1, DCM, Pyridine 2 and Styryl 9) is reported at a wavelength of 532 nm. The dyes show phase conjugate reflectivities in the 5 to 85% range. Polarization discrimination experiments and comparison with the Caro-Gower model suggests thermal origin of the nonlinearity. © 1992 Chapman & Hall.
