摘要： The specification and drawings present an apparatus and a method for intra-cavity harmonic generation in lasers such as solid-state lasers using a multi-resonance cavity with meniscus lenses for focusing corresponding wavelength radiation components on non- linear optical elements such as non- linear optical crystals using type I or type II phase-matching for significantly increasing efficiency of the harmonic conversion and output powers of generated harmonics. Using only type I or only type II phase -matching for all non- linear crystals may eliminate the requirement of linear-polarization on the fundamental laser wavelength generation. For example, a highly efficient UV Nd:YAG laser at 355 nm (a third harmonic of the fundamental wavelength of 1064 nm for the Nd:YAG laser) using intra-cavity triple resonance cavity and meniscus lenses has been developed using embodiments described herein.

摘要： A laser system includes an optical path having an intracavity relay telescope with a telescope focal point for imaging an output of the gain medium between an image location at or near the gain medium and an image location at or near an output coupler for the laser system. A kinematic mount is provided within a vacuum chamber, and adapted to secure beam baffles near the telescope focal point. An access port on the vacuum chamber is adapted for allowing insertion and removal of the beam baffles. A first baffle formed using an alignment pinhole aperture is used during alignment of the laser system. A second tapered baffle replaces the alignment aperture during operation and acts as a far-field baffle in which off angle beams strike the baffle a grazing angle of incidence, reducing fluence levels at the impact areas.

摘要： A tunable optical cavity constructed from a fixed mirror[214] and a movable mirror. The fixed mirror[214] is attached to a substrate[203] having a first electrically conducting surface. A support member[216] having the moveable mirror[213] supported thereon and having a second electrically conducting surface, is suspended above the substrate[203]. A circuit applies an electrical potential between the first and second electrically conducting surfaces thereby adjusting the distance between the fixed and movable mirrors. The fixed mirror[214] and the moveable mirror[213] are positioned such that the mirrors form the opposite ends of the optical cavity. The distance between the fixed mirror[214] and the moveable mirror[213] is a function of the applied electrical potential. The thermally induced vibrations are reduced by utilizing an electrical feedback circuit that measures the distance between the mirrors. The feedback circuit dynamically changes the potential between the substrate[203] and the support member[216] so as to reduce fluctuations in the cavity resonance frequency. The instantaneous cavity resonance frequency can be measured by comparing the cavity resonance frequency with a standard optical signal, or by using a circuit for measuring capacitative coupling between the support member[216] and the substrate[203]. The feedback circuit varies the potential between the substrate[203] and the support member[216] so as to reduce the fluctuations in said measured cavity resonance frequency or the capacitance. The optical cavity of the present invention can be utilized in constructing a tunable laser by including an active layer[355] for amplifying light trapped in the cavity. In the case of a tunable laser, the thermally induced fluctuations can be reduced by including an interferometer[360] or other frequency-selective device to determine the instantaneous wavelength of the light from the laser. An electrical feedback circuit[375] varies the potential between the substrate[203] and the support member[216] so as to maintain the measured instantaneous wavelength at a specified value.
