High-power and high-spatial-coherence broad-area power amplifier

A broad-area AlGaAs amplifier operating CW has delivered 425 mW of total power with 342 mW in a single lobe diverging at 1.02 times the diffraction limit (FWHM 0.483 deg, 87.4-micron actual aperture) for a master oscillator input power of 70 mW. The spatial coherence of the amplifier output is 0.97,...

Zusammenfassung:	A broad-area AlGaAs amplifier operating CW has delivered 425 mW of total power with 342 mW in a single lobe diverging at 1.02 times the diffraction limit (FWHM 0.483 deg, 87.4-micron actual aperture) for a master oscillator input power of 70 mW. The spatial coherence of the amplifier output is 0.97, and the mutual spatial coherence between the oscillator and the amplifier is 0.96.
