Taking advantage of the pump beam confinement and the excellent thermal management offered by Nd:YAG single crystal fibers, we demonstrated a maximum output power of 34 W at 946 nm for an incident pump power of 86 W. A high slope efficiency of 53% was obtained. There was no rollover observed in the efficiency curves and the maximum output power was only limited by the available pump power.
