✦ Synopsis

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 for operation around 448 nm wavelength and providing an output power of up to 1 W was utilized. F M3 L M1 M2 Resonator arrangement:
