Abstract

We show that a polarization rotation of the fundamental, associated with type II second-harmonic generation, occurs when the e-wave and o-wave inputs carry unbalanced intensities. This effect is applied to a device exhibiting a self-induced transparency. Experimental results are reported. The same effect may be used to realize an optical limiter.

Intensity-dependent orientation of the polarization plane of the output wave, after propagation through a 7-mm-long piece of KTP cut for type II SHG, for three initial positions αin of the input polarization.

Schematic drawing of the setup used to achieve a self-induced transparency. The arrows denote the input and output field orientations.

Fig. 3
Fig. 3

Numerical simulation of the intensity-dependent transparency of the device depicted in Fig. 2. The case of a 7-mm-long KTP crystal was considered. The data, given for different values of the input polarization orientation, concern the time-integrated transmission of Gaussian pulses of 30-ps duration.
