Abstract
A high energy Er3+, Yb3+:glass laser end pumped by a laser diode array emitting at 980 nm coupled to a Nonimaging Optic Concentrator (NOC) i s demonstrated. Energy up to 100 mJ and a 16% slope efficiency are ach ieved in a plano-plano laser cavity. The energy transfer coefficient f rom Yb3+ to Er3+ is estimated by a new method.
