Paper Abstract

A new heat extraction geometry for resonantly-diode-pumped Er3+:YAG lasers has been proposed. With this approach heat extraction from a laser rod is symmetrised and improved significantly, thus thermal lensing and thermo-induced aberrations of the active crystal are reduced. For proposed approach more than 10 W average has been generated both in CW and QCW mode of operation at comparable pumping conditions with nearly diffraction limited beam. Investigations on diffraction effects inside the fiber-like laser rod have been performed and theoretical background of observed phenomena have been defined. Finally results of further investigations on actively Q-switched laser will be presented.
