A normal incidence tapered laser amplifier is shown to produce more than 4.5 W optical power at 810 nm in a diffraction-limited beam. A new angled-facet tapered laser amplifier has demonstrated as much as 5 W optical power in a diffraction-limited beam at 810 nm with only a few mWs of coupled input power. Angled-facet laser amplifiers exhibit near-ideal Gaussian beam characteristics. More than 1.9 W CW is obtained in a 970 nm angled-facet tapered laser amplifier. A near-ideal beam quality factor M2 is obtained.
