HoP_5O_(14)非晶中Ho^(3+)离子~5F_4能级的双光子吸收

Two-photon absorption of 5~F_4 level of Ho^(3+) ion in HoP_5O_(14) noncrystalline

本文报道所观察到的HoP5O14非晶中Ho3+离子对调Q脉冲YAG基频1.06μm激光的双光子吸收现象,说明了由Judd和Pooler提出的自旋轨道三级微扰作用项可以解释该双光子吸收过程。

Two-photon absorption phenomenon of Ho3+ ion in HoP5O14 noncrystalline induced by 1. 06μm of Nd:YAG pulsed laser is reported. We fond it is a direct, not step by step, two-photon process storting from 5I8 state and can be ascribed to the third order perturbation resulted from spin-orbit interaction.
