Abstract

A cw Pr 3 + : Li Y F 4 laser at 639 nm pumped by a high-power GaN laser diode ( 444 nm ) is demonstrated. The highest laser power of 112 mW is achieved with an optical–optical conversion efficiency of 33.5%. Characteristics of this laser at elevated temperatures are also investigated for practical applications such as a laser projector.
