  • Room temperature 1.5 .mu.m band quasi-three-level laser
    Patent number: 4995046
    Abstract: A room temperature, 1.5 .mu.m band laser is described. The lasant material in the preferred embodiment is Er:YAG with a 1% Er.sup.3+ doping. The pumping radiation is an intense 1.53 .mu.m beam produced by a laser diode. The solid-state lasant material produced 1.5 .mu.m band radiation with high efficiency.
