摘要： A tunable laser that includes a laser amplifier and an acousto-optic filter (AOTF). The AOTF includes a waveguide having first and second ports. A first polarization filter passes light of a first polarization state, the first polarization filter being located between the laser amplifier and the first port of the AOTF. The laser also includes a first asymmetrical polarization rotator located between the first port of the AOTF and the first polarization filter. The first asymmetrical polarization rotator rotates the polarization of light traveling from the first port of the AOTF to the first polarization filter by 90.degree. while leaving unchanged the polarization of light traveling from the first polarization filter to the first port of the AOTF. A mirror reflects light leaving the second port of the AOTF back into the second port of the AOTF. A second polarization filter located between the mirror assembly and the second port of the AOTF passes light of a second polarization state which is orthogonal to the first polarization. A second asymmetrical polarization rotator is located between the second port of the AOTF and the second polarization filter. The second asymmetrical polarization rotator rotates the polarization of light traveling from the second polarization filter to second port of the AOTF by 90.degree. while leaving unchanged the polarization of light traveling from the second port of the AOTF to the second polarization filter.

摘要： A solid state system for converting the frequency of light emitted in the form of a laser beam using Stimulated Raman Scattering (SRS) and non-linear conversion. A solid Raman-active medium disposed inside the laser resonator shifts the frequency of the laser beam by a characteristic frequency of the medium to generate a Raman beam in accordance with the SRS effect. Another solid non-linear medium is disposed in the laser resonator for shifting the frequency of the Raman beam to generate an output beam at the desired frequency. The solid non-linear medium is a Second Harmonic Generator (SHG), a Sum Frequency Generator (SFG) or a Difference Frequency Generator (DFG) and can also generate an output beam corresponding to the sum output of the laser beam and the Raman beam. The solid Raman-active medium and the solid-non linear medium can be positioned inside a separate secondary resonator to achieve high conversion efficiency. The system is compatible with Q-switching and frequency tuning for ensuring suitable output beam parameters, and is well-suited for guide star applications.

摘要： A laser amplifying system is provided having a solid body arranged in a laser radiation field and including a laser active material that is pumped with a pumping light source. The solid body has a cooling surface and transfers heat created therein to a solid cooling element via the cooling surface. In this manner, a temperature gradient results in the solid body in a direction towards the cooling surface. The solid cooling element forms a carrier for the solid body. The laser radiation field propagates approximately parallel to the temperature gradient in the solid body. By enabling heat to be transferred to the solid cooling element via the cooling surface, this structure enables the solid body to be pumped at a high pumping power. Further, since the laser radiation field propagates approximately parallel to the temperature gradient in the solid body, the radiation field sees the same temperature gradient in all cross-sectional areas. Thus, the temperature gradient does not lead to an adverse effect on the beam quality of the laser radiation field at high pumping power.

摘要： In a laser control arrangement for tuning a laser a portion of the optical signal exiting a resonator is directed to the input of an optical frequency routing device. The routing device has a plurality of outputs each for receiving one of the frequencies supplied by the laser. Each output is coupled to a photodetector. When the laser emits a frequency of light corresponding to one of the resonant frequencies of the resonator, the resonant frequency will appear on one of the outputs of the routing device and will be detected by the photodetector coupled to that output.
