摘要

A high-power cw end-pumped laser device is demonstrated with a slab crystal of Nd:GdVO₄ operating at 1063 nm. Diode laser stacks at 880 nm are used to pump Nd:GdVO₄ into emitting level ⁴F_3/2. The 149 W output power is presented when the absorbed pump power is 390 W and the optical-to-optical conversion efficiency is 38.2%. When the output power is 120 W, the M² factors are 2.3 in both directions. Additionally, mode overlap inside the resonator is analyzed to explain the beam quality deterioration.
