三光子泵浦钠蒸汽中的光解离受激辐射

The Photodissociation Stimulated Radiation Pumped by Three Photons in Sodium Vapor

该文报道了用波长为 579.5- 586 .3nm的脉冲激光泵浦钠原子 -分子系统 ,始终可探测到分别对应于 4D→ 4P和 4P→ 4S的红外受激辐射的实验结果 ,测量了缓冲气体对红外受激辐射信号强度的影响。分析表明 ,实验中钠原子 4D态的布居主要是分子的光解离过程造成的 ,而非原子。

This paper reports the results about the generationof the infrared stimulated radiation of 4D→4P、4P→4S using pulse laser with the wavelength range of 579.5-586.5nm. The influence of buffer gas pressure on infrared stimulated radiation is measured. The population of 4D state of atomic sodium is caused by the photodissociation process in molecular sodium.
