Abstract :
Summary from only given. Strong thermal lensing of Nd:YAG rods limits the output power under high-quality beam generation. In this work, we demonstrated a power scaling of Nd:YAG rod laser over 1-kW while maintaining high-beam-quality and high-efficiency by cascaded-coupling of bifocusing compensation resonators.
