Diode-pumped Pr:YAP lasers

Spectroscopic properties and laser output results of Pr-doped YAlO3 material under 1-W GaN-laser-diode pumping at various resonator arrangement (linear, V-folded, and microchip configuration) are reviewed and compared. Continuous output power of up to 140 mW in the near-infrared spectral range at 747 nm wavelength as well as 45% slope efficiency (with respect to absorbed pump power) and intracavity frequency doubling resulting in 12.3 mW blue emission is reported.
