We broaden the linewidth of an external cavity diode laser using frequency-shifted feedback from an intracavity acousto-optic modulator. The configuration employed allows for wider tunability than has been previously reported, allowing for easy tuning to the D1 or D2 line of 85Rb and 87Rb. We demonstrate the usefulness of the laser for optical pumping of Zeeman-split lines in the kilogauss regime.
