Description
  • We report efficient continuous-wave laser operation of laser-diode pumped Pr:YAlO3 crystal in the power-scaled resonator arrangement. Using two pumping GaN-laser-diodes emitting at 448 nm wavelengths with a maximum output power of 1 W each, 290 mW of Pr:YAlO3 output power in the near-infrared spectral region (747 nm) with oscillation threshold of about 500 mW has been reached. The maximum absorbed pump power was approximately 1.5 W resulting in the slope efficiency of 28 %. Moreover, switchable laser operation at two wavelengths (747 nm and 720 nm) has been demonstrated employing the broadband laser resonator mirrors in connection with the tuning element (Lyot filter).
