Abstract
YLiF4 is widely known as the material of choice, from an application point of view, whenever high beam quality or high pulse power is requested. Side-pumped Nd:YLiF4 laser have achieved record efficiencies, even higher than longitudinally pumped Nd:YLF lasers, thanks to a novel technology developed at our lab. Here we demonstrate a record 66% conversion efficiency from qcw to Q-switched operation whilst maintaining diffraction limited beam quality.
