Abstract

We report efficient cw laser operation of laser diode pumped Pr3+-doped LiYF4 crystals in the visible spectral region. Using two InGaN laser diodes emitting at λP=443.9nm with maximum output power of 1W each and a 2.9-mm-long crystal with a doping concentration of 0.5%, output powers of 938mW, 418mW, 384mW, and 773mW were achieved for the laser wavelengths 639.5nm, 607.2nm, 545.9nm, and 522.6nm, respectively. The maximum absorbed pump powers were approximately 1.5W, resulting in slope efficiencies of 63.6%, 32.0%, 52.1%, and 61.5%, as well as electro-optical efficiencies of 9.4%, 4.2%, 3.8%, and 7.7%, respectively. Within these experiments, laser diode-pumped laser action at 545.9nm was demonstrated for what is believed to be the first time.
