Abstract :
We report the wavelength beam combining of an array of high-power high-brightness 970-nm slab-coupled optical waveguide lasers. A 50-W peak power under quasi-continuous-wave (CW) operation was measured in an output beam with a beam quality of Mx,y 2=1.2, and 30 W under CW operation was measured with a beam quality of Mx,y 2=2
