Abstract

We use semiconductor laser amplifiers and a photorefractive crystal to generate a high-power, diffraction-limited laser beam at 860  nm. Using 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, we also demonstrate efficient beam coupling, showing that this technique is easily extended to semiconductor amplifier arrays.

The vertical scales are different in (b) and (c). The pump beam is seen to amplify the signal beam without causing any measurable distortion.
