摘要： The present invention uses a laser apparatus capable of selecting a wavelength of light to be outputted from a plurality of wavelengths, including: a branching unit which is formed of a polarizer (804) and is configured to branch an optical path formed in a resonator including a reflecting unit having a plurality of fixed reflecting planes and an output mirror (802), into a plurality of optical paths, thereby forming a common optical path (809) having an end defined by the output mirror (802) and a plurality of optical path branches (810,811) each having an end defined by any one of the reflecting planes (807,808); a laser medium (803) disposed in the common optical path (809); and a selecting unit (805) configured to select, from the plurality of optical path branches (810,811), an optical path branch which corresponds to a wavelength of light to be outputted. The selecting unit (805) may be a Pockels cell which can take in addition the function of a Q-switch.

摘要： According to the present invention there is provided a laser with compact planar ring cavity that produces unidirectional laser oscillation without using intracavity elements, and which can operate in single-frequency regime. A special prism is used as output coupler and the properties of internal reflection in this prism are used to select one of the two possible oscillation directions of the ring cavity. The compact design, without intracavity elements to enforce unidirectional oscillation, allows higher output powers to be achieved. Stable single- frequency operation is achieved by the combined use of frequency selective elements, such as volume Bragg gratings, etalons, or birefringent filters, with a compact design of the cavity, which can include a monolithic structure, and the use of structural materials with low thermal expansion coefficient.

摘要： Described are laser systems for treating skin. The system includes a first solid-state laser for producing a first output beam, a second solid state laser for producing a second output beam, and a delivery device for directing the second output beam to a target region of skin. The second solid state is adapted to absorb a first part of the first output beam for generating excitation in a rare-earth doped gain medium to produce the second output beam. The second output beam is for treating the skin.
