利用HCD灯测量Gu亚稳态寿命
Lifetime measurement of Cu metastable states by meansof HCD lamp
【摘要】 <正>铜原子能级中存在着两个亚稳态能级(4d94s22D3/2和4d94s22D5/2。它们分别是铜蒸气激光器578.2nm和510.6nm激光跃迁的下能级。过去已经在CuCl正柱放电管中测量过这二个亚稳态能级的寿命,在不同的条件下,得到的结果也不尽相同,大致在10到100μs的范围内。利用HCD灯,我们发展了一种新的利用窄脉冲放电激发HCD灯产生Cu亚稳态粒子并在放电结束后测量共振激光感生荧光强度随激光脉冲对放电脉冲延迟时间的衰减关系来测量亚稳态寿命的方法。这里的激光波长共振于下能级为亚稳态的跃迁,即510.6nm:
【Abstract】 The lifetime of Cu metastable states 2D3/2 and 2D5/2 are obtained by measuringthe laser-induced fluorescence dependence of delay time on the narrow pulse discharge HCD lamps. This method is simple and has other advantages and great potential.
