  Two recently commissioned infrared beamlines on the 1.4 bending magnet port
at the Advanced Light Source, LBNL, are described. Using a synchrotron as an IR
source provides three primary advantages: increased brightness, very fast light
pulses, and enhanced far-IR flux. The considerable brightness advantage
manifests itself most beneficially when performing spectroscopy on a
microscopic length scale. Beamline (BL) 1.4.3 is a dedicated FTIR
spectromicroscopy beamline, where a diffraction-limited spot size using the
synchrotron source is utilized. BL 1.4.2 consists of a vacuum FTIR bench with a
wide spectral range and step-scan capability. This BL makes use of the pulsed
nature of the synchrotron light as well as the far-IR flux. Fast timing is
demonstrated by observing the pulses from the electron bunch storage pattern at
the ALS. Results from several experiments from both IR beamlines will be
presented as an overview of the IR research currently being done at the ALS.
