求助!帮忙翻译一段摘要（汉译英），在线等！

不要翻译工具翻译！
激光晶体作为固体激光器的主要工作物质，因其拥有比其他材料更加优异的各种特性而发展成为激光技术研究重点。Nd:YAG晶体是目前最常用和研究最成熟的一种激光晶体，目前各种其他材料的评价都与Nd:YAG相比较。为适应激光技术的快速发展，近年来围绕应用需求掀起了一场探索新型激光晶体和重新评价现有激光晶体的热潮。其中，光学均匀性是影响激光晶体质量的一项重要因素，因此在评价激光晶体质量过程对光学均匀性的测量是必不可少的。本文的目的就是研究和设计一种能定量测量激光晶体光学均匀性的方法。
本文的主要完成的内容有：（1）综述了激光技术的概念、激光器分类及其工作物质。（2）概括了激光晶体分类，发展和应用，重点研究和分析了Nd:YAG晶体的能级结构、光谱性能以及物理化学特性。（3）提出光学均匀性的概念，阐明了光学均匀性对激光晶体激光性能的影响，并分析影响光学均匀性的主要因素和造成光学不均匀的生产工艺条件，以及目前国内外检测光学均匀性的方法。（4）建立在以上的基础上，完成对“用迈克尔逊干涉仪测量激光晶体光学均匀性”的方案设计和原理分析，并成功最终测量出Nd:YAG晶体的光学均匀性为 。这证明了了该方法的可行性、合理性。

Answer 1

The laser crystal takes solid state laser's prime task material, because it has compared to a other material more outstanding each characteristic develops into the Laser Technology research key. The Nd:YAG crystal is most commonly used at present and studies the maturest one kind of laser crystal, at present each other material's appraisal compares with Nd:YAG. For the adaptation Laser Technology's fast development, has raised an exploration new laser crystal in recent years regarding the application demand and appraises the existing laser crystal the upsurge. And, optics uniformity affects the laser crystal quality an important attribute, therefore in the appraisal laser crystal quality process to the optics uniform survey is essential. This article goal is studies and designs one kind to be able the quantitative measurement laser crystal optics uniform method.
This article mainly completes the content includes: (1) summarized the Laser Technology concept, the laser classification and the operation material. (2) summarized the laser crystal classification, the development and the application, studied and has analyzed the Nd:YAG crystal energy level structure, the spectrum performance as well as the physical chemistry characteristic with emphasis. (3) proposed that the optics uniform concept, had expounded optics uniformity to the laser crystal laser activity's influence, and analyzes the influence optics uniform primary factor and creates optics non-uniform technique of production condition, as well as present domestic and foreign examination optics uniform method. (4) establishes in the above foundation, completes right “abdicates the interferometer measurement laser crystal optics uniformity with Michael” the project design and the principle analysis, and succeeds the final survey Nd:YAG crystal optics uniformity is. This has proven this method feasibility, the rationality.
