摘要： An apparatus for maintaining a crystal at a precisely controlled operating temperature over extended periods of time without significant thermal degradation of the crystal. The apparatus has thermally conducting walls. The walls define an inner hermetically sealed chamber for the crystal. Input and output windows are hermetically sealed to the input and output ends of the chamber. The inner surfaces of these windows are maintained at the operating temperature of the crystal to prevent fogging of the windows. Flexible thermal conducting layers are used between the crystal surfaces and the walls of the chamber to achieve uniform and continuous thermal contact therebetween, without mechanical stress to the crystal. The structure provides fast thermal response, controlled temperature in the crystal interaction region and stability of operation over extended periods of time. In one preferred embodiment, the crystal is held in suspended position within the chamber between a pair of spring-loaded plungers. Other embodiments and options are also disclosed.

摘要： The present invention comprises a method and apparatus to increase the efficiency of photovoltaic conversion of light into electrical power and to achieve operation at higher optical power and therefore higher electrical power. Preferred embodiments increase the efficiency of photovoltaic power conversion of any source of a beam of photons by spatially dividing the beams into a plurality of individual beamlets, each beamlet focusing on an active photovoltaic region. The preferred architecture of the apparatus of the invention comprises spatially separated photovoltaic cells to substantially match the pattern of the spatially separated plurality of beamlets. Preferred embodiments result in a significant reduction in ohmic losses and current shunting, thereby increasing photovoltaic conversion efficiencies.

摘要： A solid state pump cavity comprising a laser rod encased by diffusion bonding inside an outer cladding. The outer cladding provides the ability to efficiently conduct heat away from the laser rod. The outer cladding is also configured to absorb spontaneous laser radiation that would otherwise be re-amplified by the laser rod. Diffusion bonding of the outer cladding to the laser rod forms a seamless optical boundary between the outer cladding and the laser rod. An alternative embodiment of the pump cavity comprises multiple segments of laser rod and outer cladding assemblies coupled together with undoped sections that are diffusion bonded to the ends of the laser rod and outer cladding assemblies.

摘要： A thin disk laser includes a thin disk of a host material incorporating a laser gain medium. The disk has opposite first and second surfaces, at least one of which is non-planar. The first surface is coated with a high reflectivity coating. The second surface has an anti-reflection coating thereon. The shape and mounting of the laser is such that mismatch of the coefficients of thermal expansion between the disk laser and the mount does not affect scaling of the laser to larger size disks for higher power lasers.

摘要： A laser comprising a master oscillator and a loop phase conjugate mirror (Loop-PCM) for substantially eliminating transient relaxation oscillations to instead form controlled sustained pulsations. In a preferred embodiment suitable for material processing applications with high power requirements, the master oscillator is part of a Phase Conjugate Master Oscillator Power Amplifier (PC-MOPA). A method for processing a material using a Loop-PCM by determining and using an optimal pulse fluence, duration and spacing is provided. Using pulses of the kind which are produced by the transient, and normally not desirable, relaxation oscillations common to Nd:YAG and other lasers, relaxation oscillations with controllable pulse duration, repetition rate and duty cycle are generated, making it ideal for materials processing.

摘要： An optical beam is made closer to diffraction limited by coupling it into a multi-mode guide, such as an optical fiber, of sufficient length to generate a stimulated Brillouin scattering (SBS) return beam with improved divergence. For this purpose the term .DELTA.kL is made substantially greater than .pi., where .DELTA.k is the difference in propagation vectors between the input and SBS beams, and L is the mutual interaction length of the input and SBS beams within the fiber. Beam amplification can also be provided by coupling a plurality of low power input beams that have respective wavelengths within the fiber's SBS linewidth into the fiber so that each of the input beams transfers energy into the SBS beam, which emerges with a power greater than that of any of its inputs. The beam cleanup and amplification functions are capable of operating with continuous wave or pulsed inputs.
摘要翻译：通过将光束耦合到具有足够长度的多模引导件（例如光纤）中，使光束更接近衍射，以产生具有改善的发散的受激布里渊散射（SBS）返回光束。为此，术语DELTA kL基本上大于pi，其中ΔTAk是输入和SBS波束之间的传播矢量的差，L是光纤内的输入和SBS波束的相互作用长度。光束放大还可以通过将具有光纤SBS线宽内的各个波长的多个低功率输入光束耦合到光纤中来提供，使得每个输入光束将能量传递到SBS光束中，SBS光束的功率大于其任何投入。光束清除和放大功能能够连续波或脉冲输入。
