摘要：
A wavelength separating element is provided for separating a converted beam from a fundamental beam in an NLFC device, wherein the converted beam has a wavelength different from a wavelength of the fundamental beam. The wavelength separating element includes a first mirror surface and a second mirror surface opposite to the first mirror surface. The first and second mirror surfaces may have a high reflectivity of the converted beam relative to a reflectivity of the fundamental beam, and the first and second mirror surfaces are configured such that the fundamental and converted beams undergo multiple reflections between the first mirror surface and the second mirror surface to separate the converted beam from the fundamental beam. The fundamental and converted beams undergo at least three reflections at the first and second mirror surfaces, and/or undergo at least two reflections at one of the first mirror surface or the second mirror surface.
摘要（中）：
提供一种波长分离元件，用于在NLFC装置中将转换光束从基础光束分离，其中转换光束具有与基础光束的波长不同的波长。 波长分离元件包括第一镜面和与第一镜面相对的第二镜面。 第一和第二镜面可以具有相对于基本光束的反射率的转换光束的高反射率，并且第一和第二镜面被配置为使得基本光束和转换光束在第一镜面和第二镜面之间经历多次反射 第二镜面以将经转换的光束与基础光束分离。 基本光束和转换光束在第一和第二反射镜表面上经历至少三次反射，和/或在第一反射镜表面或第二反射镜表面之一上经历至少两次反射。
