摘要: 本文根据激光术语国家标准和ISO 国际标准对某些常用激光术语概念的理解与应用问题进行了讨论,并针对国内外科技期刊和专著经常将脉冲功率与峰值功率混为一谈的问题提出了质疑,同时也指出了在激光术语使用过程中存在的其它错误现象,分析了产生类似错误的原因并给出了规范的使用方法。最后,以脉冲激光器术语定义为例通过脉冲激光振荡过程的物理原理分析提出了关于该术语定义的一些修改考虑与建议。

Abstract: For the consistency with the national standard and ISO international standard on laser vocabulary and symbols, this paper discusses the comprehension and usage problems of some ordinary terminologies for laser. The paper oppugns the misuse between pulse power and peak power often used in certain papers published in science and technology magazines as well as academic monographs, meanwhile indicates the other improper phenomenon in writing papers, analyzes the reason of misuse and gives the canonical usage direction. Finally, we propose the modified advisement and suggestion on a pulse laser standard definition accoding to physical resonant process of the pulse laser.
