Mj. Lim et al., IMPROVED DESIGN OF A FREQUENCY-SHIFTED FEEDBACK DIODE-LASER FOR OPTICAL-PUMPING AT HIGH MAGNETIC-FIELD, Optics communications, 147(1-3), 1998, pp. 99-102
We broaden the linewidth of an external cavity diode laser using frequ
ency-shifted feedback from an intracavity acousto-optic modulator. The
configuration employed allows for wider tunability than has been prev
iously reported, allowing for easy tuning to the D1 or D2 line of Rb-8
5 and Rb-87. We demonstrate the usefulness of the lasts for optical pu
mping of Zeeman-split lines in the kilogauss regime. (C) 1998 Elsevier
