P. Besnard et al., POLARIZATION SWITCHING IN A MICROCHIP NDYAG LASER USING POLARIZED FEEDBACK, Journal of the Optical Society of America. B, Optical physics, 10(9), 1993, pp. 1605-1609
Lasers that are almost optically isotropic may operate on more than on
e polarization mode. Here we report on the polarization states of micr
ochip YAG lasers, their control by polarized feedback, and the dynamic
s of the polarization flips. Switching and polarization relaxation osc
illations are observed, both of which are much faster than the inverse
of the population decay rate.
