Power-scaled Pr:YAlO3 Laser at 747 and 720 nm Wavelengths
Original language description
We report efficient continuous-wave laser operation of a laser-diode pumped Pr:YAlO3 crystal in a power-scaled resonator arrangement. Using two pumping GaN-laser diodes emitting at 448 nm wavelength with maximum output power of 1 W each and a 5 mm long Pr.0:6 at:%/:YAlO3 crystal, 290 mW of output power in the near-infrared spectral region (747 nm) with an oscillation threshold of about 500 mW has been reached. The maximum absorbed pump power was 1.5 W, resulting in the slope efficiency of 28%. Moreover,laser emission at two transitions in the visible part of the electromagnetic spectrum (747 and 720 nm) has been demonstrated employing the broadband laser resonator mirrors in connection with the tuning element (Lyot filter).
