Diode-pumped 134-μm Nd^3+:YAlO_3 laser

Abstract
We have pumped Nd3+:YAlO3 lasers with a 40-stripe, 500-mW, 807-nm diode laser. Maximum output powers at 1.34 µm of 26 mW multimode and 20 mW in a single transverse mode were achieved. The several longitudinal modes had a total spectral width of ~0.4 nm.
