摘要： An optical system includes a diode pump source and a thin disk gain media. The thin disk gain media has first and second surfaces and is made of a material with an anisotropic thermal expansion. At least one of the first and second surfaces is a cooling surface. The thin disk gain media is cut at an angle to provide substantially the same thermal expansion coefficient in all directions lying in a plane that is parallel to the cooling surface. An optical coupler is positioned between the diode pump source and the thin disk gain media to direct an output from the diode pump source to the thin disk gain media.

摘要： In order to effectively solve thermal distortion problems and obtain high-power TEM00-mode operations for DPSS lasers, two major steps are presented in this invention. First, novel multipass pumping approaches and corresponding engineering designs have been developed for slab lasers and thin-disk lasers. They are characterized by using multipass and zig-zag pumping paths and confining pumping beams substantially via total-internal-reflection (TIR) to significantly reduce multiple reflection losses. Second, a zig-zag slab laser in combination with a beam-expanding cavity is employed to realize mode-matching pumping and maximize the energy extraction from laser slabs. It also leads to achieving high-power intracavity frequency conversions over wide spectral ranges and producing red and blue visible lasers with the aid of minimizing spatial hole burning. Besides, the invented optical multipass geometry and TIR-guide constructions can also be utilized for pumping rod lasers, fiber lasers and fiber amplifiers, and for optical amplifiers and optical or spectral detectors.
摘要翻译：为了有效地解决热失真问题并获得DPSS激光器的大功率TEM00模式操作，本发明提出了两个主要步骤。首先，为平板激光器和薄盘激光器开发了新颖的多通道泵浦方法和相应的工程设计。它们的特征在于使用多通道和Z字形泵浦路径，并且基本上通过全内反射（TIR）限制激励光束，以显着减少多重反射损耗。第二，采用与光束扩展腔结合的锯齿状平板激光器实现模式匹配抽运，并使激光板的能量提取最大化。它还导致在宽光谱范围内实现高功率腔内频率转换，并借助于最小化空间孔燃烧产生红色和蓝色可见激光器。此外，本发明的光学多通道几何形状和TIR引导结构也可用于泵杆激光器，光纤激光器和光纤放大器以及光学放大器和光学或光谱检测器。

摘要： The solid state laser comprises the laser medium 11 for absorbing the pumping light 12 from the LD 10 and generating or amplifying the light having a predetermined wavelength and a heat sink comprising the first block 15a, the second block 15b and the third block 15c for aligning the laser medium 11, cooling the laser medium 11 and reflecting the pumping light 12. The laser medium 11 has an arcuate light incident surface A and a flat reflection portion. The pumping light 12 having a diffusing angle is converted into parallel light by the light incident surface A, thereby pumping the laser medium 11 uniformly. The flat reflection portion makes it easy to align laser medium 11 having anisotropic characteristic and helps to efficiently pump the laser medium 11 by reflecting the reflection light substantially in parallel with the incident light.

摘要： 1. Solid state laser amplifier system 2.1 Solid state laser and solid state laser amplifier system having a good beam quality, which are optically excited using semiconductor lasers, requires a very costly beam shaping optical system for the radiation of the semiconductor lasers. In addition, the beam quality deteriorates at high laser power. 2.2 A non-laser-active solid (2) is connected to a laser-active solid (1) which has a reflective layer system (3) and is cooled by a cooling member (4). Parallel isothermal planes are created in laser-active solid (1) which are passed through by laser beam (8) at a shallow angle. In this manner, a compact laser beam amplifier system is created which functions without a costly beam shaping optical system for semiconductor laser (5), and has a good beam quality even at high power. 2.3 The fields of application include lasers for materials processing, the medical field, measuring technology and telecommunications.
