Sum-frequency mixing of an 808 nm broad area laser (BAL) with a build-in grating structure for spectral control and a 1064 nm solid-state laser is experimentally investigated. The spectrally improved 20 ΞΌm wide BAL can deliver up to 700 mW of output power with an M 2 of 1.4 and 5.3 in the fast and s
