共振光泵浦X光激光机制的研究

THE STUDY OF RESONANT PHOTO-PUMPING SCHEME

研究了光共振激发机制的动力学过程，以及为达到高增益、维持较长的增益时间并有较大反转率所需创造的温度、密度目标区域。给出有效泵浦光子数与增益、反转率、衰减常数的关系，及其与人射光功率密度的关系；并初步估计泵浦源必须满足的某些要求。研究结果表明，只要找到共振对，光共振激发机制的实现是可能的，但自共振机制则难于实现。最后，给出了Ｚ定标律。

We study the kinetics of lasing ions and the required electron temperature and density conditions for the lasing plasma media in resonant photo-pumping scheme.The relations between the effective pump photoslmode and gain, inverse factor and decay factor are obtained.Some conditions which the pump radiation source must satisfy are given. As a result of study,the photo-pumping scheme is possible to demonstrate if resonant line pairs are found,while the auto一resonant photo一pumping is difficult.Finally,Z-scaling law is presented.
