laser levels meaning in English

激光能级
激光水平仪
雷射水平仪

Upper laser level
上限激光电平
A co2 laser with the optimized resonator is made and to be proved by experiments . this dissertation focus on the following problems : the kinetics process of the cvl and the co2 laser , the rate equations for the laser level population , electron temperature and electron density
本文的重点是：阐述清楚铜蒸汽激光和二氧化碳激光的动力学过程，定量描述激光能级的粒子数速率方程、电子温度和电子密度等速率方程
The second part is about co2 lasers . we first discuss the mechanisms of population inversion , including excitations and relaxations ( electron collision excitation , resonance transition excitation impacted by excited n2 molecules , the relaxation of both the lower - upper laser levels and the lowest level of co2 )
首先，讨论了二氧化碳激光粒子数的反转机理，包括电子碰撞激励、激发态n2分子等共振转换激励过程，激光上下能级co2 ( 00 1 ， 10 0 )以及最低能级co2 ( 0110 )的弛豫过程等几个方面
