We report a continuous-wave end-pumped Nd:YVO4 zigzag slab laser with multilayer amplified spontaneous emission (ASE) absorbing coatings.The coatings are deposited on the slab faces.A five-layer structure consists of SiO2-Ti-SiO2-Ti-Au,and the thicknesses are 2520nm,10nm,160hm,24nm and 200nm,respectively.The designed coatings show good performance for the ASE control in the experimental tests.A stable-unstable hybrid laser oscillator along orthogonal directions in the slab aperture is further configured,achieving the 117 W output at a pump of 328 W.The beam quality factors M2 in the unstable direction and stable direction are 1.57 and 1.66,respectively.
