激光喇曼法测量室温下N2(v=1)的振动弛豫寿命
Laser-Raman measurement of vibrational relaxation time of N2 at room temperature
摘要
在强的CW DF激光作用下,氮分子在高压下因压力诱导吸收而被泵浦到v=1能级.用Ar~+激光作光源,测量N_2的反斯托克斯喇曼散射,从而测得室温下N_2的平均振动弛豫寿命(?)为0.46±0.30soc?atm.
Abstract
N2 molecules at high pressure were pumped into v = 1 level with a high power CW DF laser as a result of pressure-induced absorption. Using an Ar+ ion laser as the source we measured the anti-Stokes Raman scattering and obtained the vibrational relaxation time of N2 at room temperature to be 0.46±0.30 sec?atm.
