Title: High-power dual-rod Yb:YAG laser

Abstract

We describe a diode-pumped Yb:YAG laser that produces 1080 W of power cw with 27.5% optical optical efficiency and 532 W Q -switched with M{sup 2}=2.2 and 17% optical-optical efficiency. The laser uses two composite Yb:YAG rods separated by a 90 degree sign quartz rotator for bifocusing compensation. A microlensed diode array end pumps each rod, using a hollow lens duct for pump delivery. By changing resonator parameters we can adjust the fundamental mode size and the output beam quality. Using a flattened Gaussian intensity profile to calculate the mode-fill efficiency and clipping losses, we compare experimental data with modeled output power versus beam quality.
