Abstract: Efficiencies of ~ 1.5–2% were achieved in YSGG:Cr:Nd lasers utilizing resonators insensitive to thermal birefringence in the active element under conditions of frequency doubling in a KTP crystal. The pulse output energies were 400 (240) mJ and the pulse repetition frequencies were 25 (50) Hz. Prospects for further improvement in the output parameters of these lasers were demonstrated.
