激光诱导荧光能级寿命检测中磁场的干扰

Magnetic Interfere on Time-resolved Laser Induced Fluorescence Measurements

在孔阴极放电激光诱导荧光氩原子ＡｒＩ５ｐ［３／２］２能级寿命检测中，当加强外磁场于其观察方向，被测能级寿命随磁场强度的增加而缩短。其自然能级寿命被确定为１２０ｎｓ。

The measured lifetimes shortened according to the intensity of the magnetic field in hollow cathode discharge laser induced fluorescence Ar I 5p [3/2]2 lifetime detection when strong external magnetic field was applied on the direction of observation.Its natural lifetime was decided to be 120 ns.
