We report high-power laser operation that was achieved with a-cut and c-cut crystals. Up to of π-polarized output power was generated from an a-cut, uncoated crystal with an optical conversion efficiency of 59%. The highest slope efficiency was 80%. Laser oscillation obtained with c-cut crystal was also linearly polarized, with two orthogonal polarization components along  and directions. The highest output power achieved was , with an optical conversion efficiency of 33% and a slope efficiency of 40%.
