激光效率 meaning in English

lasing efficiency

The dependence of cw df / hf cl performance on the flow - field parameters in f & d2 / h2 reacting zone , which act as criterion to nozzles design , has been inversely educed on the light of original formula of gain coefficient , output power and laser efficiency
从增益系数、输出功率和激光效率的基本模型公式出发，逆推得到了df hf化学激光器性能对光腔中f和d 。川。反应区流场参数的依赖关系。
The first ytterbium - doped yttrium - aluminum garnet ( yb : yag ) laser action was reported back in 1965 using a lamp - pumped rod at 77 k . because of poor spectral overlap of the lamp with the the trivalent ytterbium ion ( yb3 + ) absorption band , the efficiency was very low . lamp - pumped nd : yag lasers fared better due to the multiple pump bands of neodymium
但yb3 +离子的泵浦吸收带与闪光灯光谱匹配很差,导致其激光效率很低;而nd : yag的激活离子( nd3 + )有多个泵浦带与闪光灯光谱匹配,较好适应了灯泵浦的需要,长期占据了固体激光器的主导地位。
