Abstract

We report efficient pulsed operation of a b-axis Nd:YAlO3 laser rod at 1.08 and 1.34 μm side-pumped by laser-diode arrays. Optical slope efficiencies of 27% and 20% were obtained at these wavelengths. Polarized absorption spectra were taken for Nd:YAlO3 along the three principal axes in the region of the pump bands from 780 to 830 nm.
