We use an argon-ion laser, modulated at two or more frequencies, to pump a
multimode dye laser. Time series of the modulated pump and the output of
the dye laser are collected simultaneously. The dye-laser response is
analyzed for the presence of chaotic and quasiperiodic attractors. We
estimate and compare the correlation dimension and the order-2 Renyi
entropy of both the modulated-pump and dye-laser output signals using an
embedding-space technique. Fourier transforms of the time series are also
