In a preferred embodiment, the ultraviolet optical isolator comprises: an input polarizer for linearly polrizing an input beam of ultraviolet light in a first plane of polarization; means for rotating the plane of polarization of the linarly polarized ultraviolet light from the input polarizer by substantially 45 degrees in a first direction; a Faraday rotator including an optical element made of a KDP-isomorph crystal in which the plane of polarization of the rotated linearly polarized ultraviolet light from the rotating means is rotated about an optical axis of the optical element, a plurality of permanent magnets sequentially coupled together with altnerating polarities for developing a magnetic field along the optical axis of the optical element in order to cause the optical element to rotate the plane of polarization of the rotated linearly polarized ultraviolet light from the rotating means by substantially another 45 degrees in the first direction to a second plane of polarization substantially orthogonal to the first plane of polarization, and means for moving the optical element so that the optical element is always enclosed by the plurality of permanent magnets; and an output polarizer for outputting the ultraviolet light in the second plane of polarization.

摘要： An unstable resonator laser cavity providing high power radiation with diaction-limited divergence and narrow-bandwidth comprises a gain medium for generating and amplifying laser radiation optically coupled to a reflector via a frequency narrowing element for providing feedback and bandwidth-narrowing of the laser radiation travelling between the gain medium and the reflector. A telescopic ring is optically coupled to the gain medium opposing the reflector. The telescopic ring comprises a polarized beam splitter, which transmits a first polarization polarized laser radiation into the telescopic ring travelling in a first direction and reflects a second polarization polarized laser radiation into the telescopic ring travelling in a second direction; first and second rotators for rotating the first polarization polarized laser radiation to provide second polarization polarized laser radiation travelling in the first direction; and lenses for magnifying the second polarization polarized laser radiation travelling in the first direction onto the polarized beam splitter, which reflects the second polarization polarized laser radiation produced by the first and second rotators back into the gain medium. A scraper mirror, located between the gain medium and the reflector, provides the output beam.

摘要： A laser cavity providing high power laser radiation with diffraction-limi divergence and narrow-bandwidth comprises: a stable laser cavity including a gain medium, which generates and amplifies laser radiation, optically coupled to first and second reflectors and an optical coupler; and an unstable laser cavity including the gain medium, the first reflector, the optical coupler and a scraper mirror. The scraper mirror is located between the gain medium and the optical coupler for producing an output beam. The stable laser cavity is restricted to operate on a low order TEM mode by an aperture located between the optical coupler and the second reflector. A frequency narrowing element located between the optical coupler and the second reflector narrows the bandwidth of the laser radiation in the stable laser cavity. The optical coupler couples the narrow bandwidth laser radiation from the stable laser cavity to the unstable laser cavity, thereby producing narrow bandwidth laser radiation in the output beam.
