Abstract

Lasers that are almost optically isotropic may operate on more than one polarization mode. Here we report on the polarization states of microchip YAG lasers, their control by polarized feedback, and the dynamics of the polarization flips. Switching and polarization relaxation oscillations are observed, both of which are much faster than the inverse of the population decay rate.

  11. This is at complete variance with the results given in Ref. 9. There, however, the laser was pumped near 800 nm and operated in two modes, presumably with polarization competition. Clearly such dramatic contrast between the two sets of observations invites further research.
  12. In principle the behavior of the laser should depend on the orientation of the feedback relative to the oscillating mode and to the orientation of the feedback relative to the natural modes of the free-running laser. In our microchip lasers the latter dependence does not appear to be important, and thus we have chosen a nomenclature that identifies only the orientation of the mode with respect to the polarization of the feedback; i.e., we distinguish two, not four, cases. This nomenclature is different from that used in our earlier publications.
  13. This applies to the monomode region. For high pump powers the laser becomes multimode.
