title: Efficient resonantly pumped tape cast composite ceramic Er:YAG laser at 1645 nm.
abstract: Laser operation of a composite ceramic Er:YAG rod is demonstrated at 1645 nm with a slope efficiency of 56.9% under resonant pumping at 1532.3 nm. This is believed to be the first reported composite ceramic Er:YAG laser and also the first reported use of a tape cast technique for producing laser ceramics.
