TL;DR: In this article, the authors investigated four-wave mixing in broad-area diode lasers using a phase conjugation geometry and a spectrally resolved measurement of the far field.
Abstract: Four‐wave mixing is investigated in broad‐area diode lasers. Two external fields are injected into the device using a phase conjugation geometry and the nonlinear four‐wave mixing signal observed by performing spectrally resolved measurement of the far field. By varying the injection geometry, the excited mode of the broad‐area diode can be controlled. The gain nonlinearity generates a conjugate wave within the device, thereby resulting in far‐field emission in the conjugate direction. Nonlinear conjugate signal efficiency levels of ∼−21 dB have been observed.

TL;DR: In this paper, the stable and high quality wave front conjugation of short laser pulses in azo-dye doped LC was obtained based on the conformational nonlinearity and implies that the refractive index changes arise due to the dependence of the LC order parameter on the concentration of photoinduced dye-isomers.
