Abstract:
A method for generating polarized laser output radiation with the aid of a laser resonator, said resonator having a highly reflecting resonator mirror;a radiation output device; and an active medium having an emission-bandwidth and exhibiting thermally induced birefringence, comprising: providing for a resonator having radiation fields oscillating inside only within said emission-bandwidth; subjecting the radiation fields to a polarization selection of a prescribed polarization state (p) by said radiation output device; and partially outputting only one radiation field exhibiting the prescribed polarization state (p) by said radiation output device from the oscillating radiation fields in that manner that all differently polarized radiation fields remain in the resonator in a completely reflecting fashion up to a tolerance and the remaining proportion of the radiation field of the partial output remains also oscillating inside the resonator.
