Paper Abstract

Rectangular broad area optical traveling-wave amplifiers have been demonstrated to emit 3.3 W CW of diffraction-limited output power when injected with 400 mW of Ti:Sapphire radiation. Improvement in the amplifier characteristics is realized by replacing the rectangular current-pumped contact with a flared or tapered contact, and amplifying a diverging beam. In this fashion, up to 5.25 W CW of diffraction-limited output is obtained from a 200 mW Ti:Sapphire master oscillator.
