We report observation of the effect of deep modulation of laser action in lead telluride (PbTe) at 20°K. This effect arises following two-photon pumping by C02-laser radiation and rotation of the direction of the linear polarization of the radiation aimed at the crystal. An explantion of the obtained effect is proposed.
