摘要
Conversion of near infrared laser light into green emission has been obtained in Gd3Ga5O12:Yb:Tm:Ho by a two step process: absorption from the ground states of the ions followed by a mechanism we have called the looping mechanism. The latter is composed of an absorption from the I-5(7)(Ho) excited state followed by a positive feedback process via the Tm ions. A two ion (Tm-Ho) model is given to describe the dynamics and the gain and losses of the loop are evaluated.
