Nd:YLF laser pumped at 797 nm with 68% slope efficiency

Abstract
We demonstrate a Nd:YLiF<sub>4</sub> laser emitting at the 1053nm transition while side-pumped at 797nm by a VBG equipped diode. Initially, a plane-concave cavity is employed using a total internal reflection at the crystal pump face. The laser operated in QCW-mode and produced 68% of slope and 66% of optical efficiency with 67 W of peak output power, while having a multimode beam quality. These efficiencies are the highest ever reported for the Nd:YLF<sub>4</sub> pumped at 800nm.
