Abstract
Resonantly pumped laser operation is achieved with a quantum defect (QD) of 1.5% at liquid nitrogen temperature. The laser, in-line pumped at , operated at with a slope efficiency of over 45%. This is believed to be the lowest QD eye-safe laser ever reported. CW output of over was obtained in this first experiment.
