Numerical model for pulsations in polarization of emission from a laser with an anisotropic cavity when initiated in a magnetic field

Based on equations for the evolution of the polarization density matrix for laser emission, we have shown that when a laser with an anisotropic cavity is turned on in a magnetic field higher than some critical value, we will observe a new optical effect: pulsations between the polarized and completely unpolarized states of the laser emission. In a magnetic field much higher than the critical value, practically complete suppression of polarization occurs, which may serve as a method for obtaining unpolarized laser emission. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 75, No. 1, pp. 134–142, January–February, 2008.
