摘要： A tunable laser has a solid state laser medium having an optical gain region and generates coherent radiation through a facet. A lens collects the coherent radiation and generates a collimated light beam. Components of an external cavity include a reflective surface and an optical filter, the reflective surface reflecting the collimated beam back to the lens and the laser medium, the optical filter positioned between the reflective surface and the lens and having two surfaces with a thermally tunable optical transmission band within the optical gain region of the laser medium. The optical filter (1) transmits a predominant portion of the collimated beam at a desired wavelength of operation, and (2) specularly reflects a remaining portion of the collimated beam from each surface, the collimated beam being incident on the optical filter such that the reflected collimated beams propagate at a non-zero angle with respect to the incident collimated beam.

摘要： A laser cavity two-photon spectroscopy includes a gain medium, a first reflector, a second reflector, an electrical pumping module, and a two-photon absorption cell. The first reflector is disposed at a side of the gain medium. The second reflector is movably disposed at a side of the gain medium relative to the first reflector. The electrical pumping module is electrically connected to the gain medium. Therefore, the gain medium is able to emit a light beam, which bounces back and forth between the first reflector and the second reflector and forms a laser beam through enhanced by the gain medium. The two-photon absorption cell disposed between the gain medium and the second reflector includes a plurality of two-photon absorption mediums. The two-photon absorption mediums absorb a portion of the laser beam reflected between the first reflector and the second reflector and then emit fluorescence.

摘要： A laser light source having a semiconductor laser (102) for outputting pump light, and a laser resonator wherein a solid laser crystal (104) and a non-linear optical crystal (103) are connected by optical contact and a reflection coat (106) and a reflection coat (105) are on the opposed facets of the respective crystals. GdVO4 is the solid laser crystal (104) while LiNbO3 is the non-linear optical crystal (103), and the crystal axis of the solid laser crystal (104) is inclined with respect to the z axis of the non-linear optical crystal (103) within the z-x plane of the non-linear optical crystal (103). The thermal expansion coefficients of the solid laser crystal and of the non-linear optical crystal can be approximated to each other, thereby preventing separation of the bonded laser crystal and non-linear optical crystal due to different thermal expansion coefficients when heat is generated during laser oscillation, which stops laser oscillation.

摘要： An external cavity laser apparatus includes a wavelength tuning element mounted to a carrier on the apparatus's platform. Thermal control of the platform sets an initial position of the carrier and tuning element, from which independent tuning of the element can be achieved for wavelength tuning. The carrier is formed of a liquid crystal polymer that thermally isolates the tuning element from this platform, for such independent thermo-optical tuning. The liquid crystal polymer may match the coefficient of thermal expansion of the carrier to that of the platform. The support further includes embedded electrodes, either within or on the outer surface of the carrier, which can couple from the tuning element to the controller, where in some examples such coupling is direct and without use of additional electrical traces or wire bonds.
