Abstract :
In this paper, power scaling was demonstrated with a more powerful oscillator. The oscillator generated a 550W azimuthally-polarized beam with wavelength, tuned by a tilted etalon, to achieve maximum amplifier gain. 4kW was measured from three amplifiers. More amplifiers provide higher powers and better extraction efficiency.
