泵浦辐射 meaning in English

pumping radiation

But the absorption efficiency , stokes efficiency , quantum efficiency and the superposition efficiency between pump mode and cavity mode is less than one respectively , so the local heat absorption of the crystal is quite strong , and its thermal effect is quite obvious . two measures were taken
但是，由于量子效率小于1 ，斯托克斯频移，泵浦光与基模的非完美空间重叠以及激光晶体的偏振吸收等因素积聚在晶体内的热量随泵浦辐射而变化，出现更为复杂和明显的热透镜效应。
