摘要
本文报导了1.06μm脉冲激光导致的Sm^(3+)的三光子荧光现象,解释了观察到的~4G_(5/2)的荧光是~6H_(5/2)→~6F_(9/2)的单光子吸收经无辐射弛豫在~6F_(1/2)上集聚了较大的布居,然后由此经直接双光子吸收跃迁至~6P_(3/2),再经无辐射弛豫到达~4G_(5/2)能级,形成的发光过程.
In this paper the three-photon fluorescence phenomenon of Sm3+ induced by 1.06UUUUUUUm pulsed laser beam is reported. This can be explained as two-step processes: a single-photon absorption to 6F9/2 state and non-radiative relaxation to 8F1/2 state; and then a successive two-photon absorption to 6P1/2 state and nonradiative relaxation to 4G5/2 state. A brief discussion is given.
