Abstract

Radiation characteristics of q-switch and stationary generation of end-pumped Er:YLF-laser taking into account inhomogeneous gain constant are investigated. The model of laser radiation and active media interaction at both generation cases is developed. Main spatial and energy dependences on laser resonator parameters and doping concentration in active element are presented for monopulse lasing. The stationary fundamental mode intensity dependences on pumping parameters and small signal gain constant are presented.

Keywords: erbium lasers, spatial characteristics of laser generation, diode end-pumping, stationary lasing
