小功率固体激光器的设计与研究
摘要
固体激光器从其诞生开始至今,一直是备受关注。其输出能量大,峰值功率高,结构紧凑牢固耐用,因此在各方面都得到了广泛的用途,其价值不言而喻。正是由于这些突出的特点,其在工业、国防、医疗、科研等方面得到了广泛的应用,给我们的现实生活带了许多便利。本论文从基本原理和结构介绍固体激光器,并对激光和激光器的原理和基于原理而做出的进一步的相关研究做一个大致的探讨。

DESIGN AND RESEARCH OF LOW POWER LASER
ABSTRACT
Solid state lasers from its beginning until now, has been the subject of much attention. The output energy, high peak power, compact structure, firm and durable, so in various aspects have been widely used, its value is self-evident. It is because of these outstanding features, which has been widely used in industry, national defense, medical, scientific research, to our real life with a lot of convenience. In this paper, from the basic principle and structure of the solid state laser, and the principle of laser and laser and based on the principle and make further research to make a general discussion.
KEY WORDS Laser,Solid state laser,Resonant cavity,Particle number inversion
