Abstract
We present experimental results on the selection of transverse patterns and
their dynamics in a CO2 laser with an intracavity grating. Depending on th
e parameter values, we observe different single-frequency patterns with pos
sible bistability between them. Turning on the laser within the bistable re
gion yields a switch-on to a metastable pattern, which eventually decays in
to the other stable pattern. In the bistable region, noise appears to play
an important role in the pattern dynamics over long time scales.
