Abstract
We use semiconductor laser amplifiers and a photorefractive crystal to generate a high-power, diffraction-limited laser beam at 860 mm. Usin g a single flared amplifier, we obtain 1.09 W in a diffraction-limited beam from 2.2 W of pump power. Using an array of flared amplifiers, w e also demonstrate efficient beam coupling, showing that this techniqu e is easily extended to semiconductor amplifier arrays.
