Study on Vibration-Rotation Relaxation in Highly Excited Vibrational Levels of Molecular Laser Process.

高功率分子激光器在非线性光谱学和受控热核聚变研究中有着广泛的应用需求。分子再征税基本过程的数值计算是设计高效率气体激光器的基础。本项目将对激光活性分子的碰撞诱导跃迁和振动-振动能级间的碰撞激发转移进行定量研究。特别是对分子激光高激发振动态的弛豫过程进行了详细的研究。光谱研究很好地阐明了CO_2分子的规则激光能级和序列激光能级的振动回复速率常数。

The high power molecular Laser has been in demand to be used bor nonlinear spectroscopy and controlled thermonuclear fusion research. Numerical data on thefundamental processes of molecular retaxation are essential to design the gas laser with high effeciency. In the present project, the collision induced transition and the collisional excitation transfers among vibration-votation energy levels of laser-active molecules will be guantitatively studies. Especially the relaxation process on the highly excited vibrational states of molecular laser isto be in vestigated in detail. Spectroscopic study well clarify the retaxationrate constant in vibration for regular laser level and sequence laser levels ofCO_2 molecules.
