Powerful pulse solid state laser based on potassium-gadolinium tungstate neodimium-doped crystals

摘要

The development and the investigation of generation of a powerful pulse solid-state slab laser based on potassium-gadolinium tungstate crystals with neodimium ions in unconventional resonator design realizing the mechanism of autocompensation for optical field distributions caused by an effect induced in powerful lasers active medium by pumping emission are reported. The operation efficiency of this mechanism on the pulse solid-state lasers with slab elements of rectangular cross-section is shown. A high lasing efficiency and high beam quality of the studied laser output radiation are demonstrated.
