  We demonstrate an atom laser using all-optical techniques. A Bose-Einstein
condensate of rubidium atoms is created by direct evaporative cooling in a
quasistatic dipole trap realized with a single, tightly focused CO$_{2}$-laser
beam. An applied magnetic field gradient allows formation of the condensate in
a field-insensitive $m_{F} = 0$ spin projection only, which suppresses
fluctuations of the chemical potential from stray magnetic fields. A collimated
and monoenergetic beam of atoms is extracted from the Bose-Einstein condensate
by continuously lowering the dipole trapping potential in a controlled way to
form a novel type of atom laser.
