Abstract

This paper proposes an analysis of a Yb:KYW laser emitting at 981nm intracavity pumped by a Nd:YVO4 laser operating at 914nm. It gives some guidelines to optimize the laser performance. An output power of 1W has been obtained at 981nm for a pump power of 23W at 808nm. It presents a simple and original model to deal with the line competition between 981nm and the other lines at 1000 and 1023nm and explains how a temperature increase can promote the 981nm laser emission. This approach could be useful for other lasers that are subject to line competition.
