laser threshold meaning in English
激光阈值
Examples
- The rate equation formalism is used to develop the concepts of laser threshold , population inversion and modulation response
比例方程式形式用来生成雷射临界点、能态数反转与调变反应的概念。 - The analyses given in this paper to quasi - three - level for 946 nm laser are complete . the relation between 946 nm laser transmission and optimal crystal length has been derived from the rate equations describing the population inversion and the photon density in the laser cavity in the steady - state case . the minimal claims to coating have been given on the base of contrasting 946 nm transmission with 1064 nm transmission in the condition of different cavity losses and how the pump beam radius in the laser crystal and optimal crystal length affect the laser threshold and output power of 946 nm laser has been given as well
对产生946nm谱线的准三能级结构给出了较为完整的分析，利用激光谐振腔处于稳态时的速率方程，导出了准三能级nd ： yag946nm起振时，透射损耗与最佳激光晶体长度的关系，在与1064nm透射损耗相比较的基础上，给出了不同的腔损耗情况下的最低镀膜要求，并且给出了激光阈值、输出功率和最佳激光晶体长度及泵光光斑大小的关系，这为设计室温下高效运转的946nm激光器的提供了理论基础，这种分析方法对研究此类低增益，准三能级或三能级激光系统输出特性有借鉴意义。 - The laser threshold decreases from 4 . 7w ( without external cavity ) to 3 . 6w ( with external cavity ) . with the cavity of output from zero - order diffractive beam applying to solid - state pyrromethene 567 ( p567 ) , tunable range of about 70nm from 543 - 610nm , the largest range reported as we know , had been achieved . and the highest slope efficiency of 17 . 2 % was obtained at 583nm wavelength
在使用光栅一级反馈、零级输出可调谐腔的可调谐实验中，得到了调谐范围近70nm ( 543 610nm )的激光输出，此结果在已知报道的激光调谐范围中是最宽的，输出波长为583nm时得到最高斜效率17 . 2 。
