摘要
本文报导了我们首次观察到TbP_5O_(14)非晶中Tb^(3*)离子的双光子吸收现象,发现二级理论允许的双光子吸收较强,否则则很弱,并且这些弱的双光子吸收的强度可由进一步考虑三级自旋轨道相互作用对双光子吸收的微扰贡献加以解释。
In this paper the first observation of the two--photon absorption for Tb^3+ ionin noncrystalline TbP_6O_(14) is reported. It is found that the two--photon tran-sitions which are allowed by second--order theory have rather strong intensi-ties, otherwise they are weak and can be explained by third--order theory whichtakes the contribution of the spin--orbit interaction lnto account.
