A high beam quality laser-diode end-pumped Nd:GdVO_4 slab laser

摘要

An 83 W, near-diffraction-limited LD end-pumped Nd:GdVO_4 slab laser with hybrid resonator was presented with the pumping power of 238 W, the slope efficiency and optical-to-optical conversion efficiency were 39.4 and 34.9%, respectively. At the output power of 70 W, beam quality M~2 factors were 1.2 in stable direction and 1.3 in unstable direction.
