elliptical beam meaning in Chinese

椭圆波束

However , ingaas strained - layer single quantum well lasers , optimized for low threshold current and low series resistance , have a highly elliptical beam structure emanating from the laser facet
但是报道的技术中多是针对圆对称光束或近圆对称光束。
A theoretical and experimental study of a new , efficient technique to couple a laser , emitting a highly elliptical beam , to a single - mode fiber without the use of bulk optical components is presented . the technique involves butt coupling the laser to a cylindrical lensed fiber and spherical lensed fiber
本文从理论上和实验上呈现了一个实用的耦合技术，即在没有使用分立球形光学元件的情况下将高度椭圆化的激光光束通过透镜光纤耦合到单模光纤中。
A ld pumped lbo / bbo / nd : yag 266nm all - solid - state ultraviolet laser and purple and a ld pumped ktp / bbo / nd : yag 266 nm all - solid - state ultraviolet laser were designed respectively ; 1 . 5mw and 2 . 0mw average output power were obtained respectively when maximum input power of ld was 1 . 3 w . reasons of being elliptical beam and 45 ? rotation for the beam were also explained
设计出一台lbo bbo nd ： yag266nm全固态紫外激光器和一台ktp bbo nd ： yag266nm全固态紫外激光器；用1w的ld作为泵浦源，在最大抽运功率为1 . 3w时，分别获得了平均功率为1 . 5mw和2 . 0mw的266nm紫外输出。
