摘　　要：We report a continuous-wave end-pumped Nd:YVη4 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 2520 nm,10 nm,160 nm,24 nm and 200 nm,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 and1.66,respectively.
