在宽带XeCl激光泵浦的钡蒸气中,观察到波长分别为472.6nm,582.6nm和648.3nm的碰撞诱导受激辐射以及波长为475nm的受激喇曼散射.碰撞锈导受激辐射脉宽为3ns左右的自终止型短脉冲,其强度随缓冲气体压力的升高而上升.喇曼光脉冲前沿与泵浦光脉冲前沿之间有长20ns的时间延迟,喇曼转换效率随缓冲气体压力的升高而下降

The stimulated collision-induced fluorescence (SOF) at wavelengths of 472.6nm, 582.6nm and 648.3nm, as well as Raman-shifted radiation at wavelength of 475nm were observed in barium vapor pumped by broadband pulse of the XeOl laser. The SCF was found to be self-termination short pulses with FWHM of 8 ns, and its internsity inoreased with buffer-gas pressure. There existed time delay aa long as 20 ns between the front edges of the pump pulse and of the Raman-shifted pulse, and the Raman conversion efficiency deoreased significantly as the buffer-gas pressure increasing.
