摘要： There is provided a rotary disk laser module including disk comprised of at least one lasing material. The lasing material may be excited by a laser excitation source, such as an optical pump beam directed onto the disk. The laser gain region contains excited lasing material and extends between the first and second surfaces of the disk. A laser generator is formed when the gain region is brought into optical communication with a laser generator. A laser generator may be a laser oscillator or a laser amplifier. The disk may move in order to enable various lasing functionality to the laser module. For instance, the disk may rotate, translate, or tilt to rotate the gain region, provide various quantum effects, or to enable heat transfer with a heat sink. A high-power laser generator may be formed by using a number of disks containing lasing material, exciting the lasing material using at least one laser excitation source, and bringing them into optical communication with a laser generator.

摘要： The present embodiment provides a thin disk laser disk element having improved direct cooling through the use of a barrier material directly attached to the high reflectivity layer of the thin disk element. This barrier is needed due to noticeable degradation of the reflectivity of the thin disk element without the barrier material. A barrier material of sapphire (crystalline Al2O3) is preferable, given a desire to have adequate thermal conductivity through the barrier material, proper matching of the coefficient of thermal expansion with the other components of the thin disk, and to save monetary costs. In another preferred embodiment, an intermediate layer is interposed between the thin disk element and the barrier material to provide improved adhesion between the barrier material and the thin disk element. Preferred crystallographic orientations for sapphire barrier material are provided as well.

摘要： Because a reflector that reflects a fundamental wave generated from a solid-state laser element and forms an optical resonator is disposed on an exit surface of a wavelength conversion element, the fundamental wave cannot be resonated and amplified in a stage before the wavelength conversion element is joined to the solid-state laser element. As a result, a problem is created in that the solid-state laser element emits low level light output, so that a relative position of the semiconductor laser and the solid-state laser element cannot properly be adjusted. In order to overcome the above problem, even in the stage before joining the wavelength conversion element to the solid-state laser element, the invention enables the semiconductor laser and the solid-state laser element to be joined by properly adjusting the relative position of the laser and the laser element. A second reflector is provided that is located opposite a first reflector of the solid-state laser element and that partially transmits through the fundamental wave emitted from the solid-state laser element and reflects the rest of the wave. The semiconductor laser and the solid-state laser element are joined together at a relative position such that the output of light having passed through the second reflector reaches or exceeds a predetermined value.
摘要翻译：因为反射从固态激光元件产生的基波形成光谐振器的反射器设置在波长转换元件的出射表面上，所以在波长转换元件为波长转换元件之前的阶段，基波不能被谐振和放大连接到固态激光元件。结果，产生固体激光元件发射低电平光输出的问题，使得半导体激光器和固体激光元件的相对位置不能适当地调节。为了克服上述问题，即使在将波长转换元件接合到固体激光元件之前的阶段中，通过适当地调整半导体激光器和固态激光元件的相对位置，能够使半导体激光器和固体激光元件接合激光和激光元件。提供了与固态激光元件的第一反射器相对的第二反射器，并且部分透射通过从固态激光元件发射的基波并反射波的其余部分。半导体激光器和固体激光元件在相对位置处接合在一起，使得通过第二反射器的光的输出达到或超过预定值。

摘要： A laser amplifier system is provided which comprises a resonator with optical resonator elements which determine a course of a resonator radiation field which propagates along an optical axis and at least one laser-active medium (LM). The resonator is designed as a split resonator and has a first resonator section which extends from a first virtual plane of separation and a second resonator section which extends from a second virtual plane of separation. The resonator sections are dimensioned optically such that the resonator radiation field has radiation field states corresponding to the same resonator modes in each of the virtual planes of separation. An amplifying unit optically independent of the resonator is arranged between the first and the second virtual planes of separation. The amplifying unit comprises the at least one laser-active medium and couples the radiation field states in a neutral manner with respect to the resonator modes.

摘要： A compact optically-pumped solid-state laser designed for efficient nonlinear intracavity frequency conversion into desired wavelengths using periodically poled nonlinear crystals. These crystals contain dopants such as MgO or ZnO and/or have a specified degree of stoichiometry that ensures high reliability. The laser includes a solid-state gain media chip, such as Nd:YVO4, which also provides polarization control of the laser; and a periodically poled nonlinear crystal chip such as PPMgOLN or PPZnOLT for efficient frequency doubling of the fundamental infrared laser beam into the visible wavelength range. The described designs are especially advantageous for obtaining low-cost green and blue laser sources. Also described design of the continuously operated laser with an electro-optic element for modulation of the intensity of the laser output at frequencies up to hundred of megahertz. Such modulation is desired for various applications, including compact projectors with high resolution.
