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