Abstract
In this paper we demonstrate an efficient dual frequency operation of a pulsed diode pumped Nd:GdVO4 laser at 1.06 μm spectral region using polarization control of the generated radiation. Generation at the commonly reported 1063 nm line with π polarization (parallel to crystal c-axis) can be changed to the 1066 nm line with σ polarization by tuning of the wave plate in the laser resonator. For pump energy of 15 mJ from laser diode the laser output energy is 5.2 mJ at 1063 nm, or 4.23 mJ at 1066 nm or 4 mJ in simultaneous dual wavelength regime. The investigation of the spatial and temporal structure of generated radiation was also performed. A source allowing wavelength selection can be attractive for applications in spectroscopy etc.
