We present an external-cavity laser diode characterized by an intracav
ity cylinder lens to compensate for the astigmatism of the laser. This
setup was applied to a broad-area laser diode operating on the D-1 li
ne of the cesium atom at 894 nm, yielding single-mode emission. A satu
rated-absorption experiment on that atomic line tested the laser perfo
rmance. (C) 1998 Optical Society of America.
