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...
In the present work we report on two wavelength generation of Pr:YAlO3 laser reached by Lyot filter tuning at room temperature. Laser emission at two transitions in the visible part of the electromagnetic spectrum (747 nm and 720 nm) has been demonstrated employing the broadband laser resonator mirrors in connection with the tuning element (Lyot filter). As a pumping source, GaN laser diode designed...
