Abstract :
A hybrid master oscillator power amplifier is realised on a small area less than 100 mm2 combining an α-DFB-laser as master oscillator and a broad area laser as power amplifier. A quasi-cw output power of P=1.6 W at the wavelength) λ=1057 nm is achieved with a beam quality factor M2 less than 2 and a spectral width less than 6 pm
