Frequency-dependent conductivity measurements are reported in the charge-density-wave state of K0.3MoO3 in the micrometer- and millimeter-wave spectral range. The high-frequency mode, the response in the MHz range, and the long-time relaxation processes are analyzed in a wide temperature range. The ac response is suggestive of different relaxation times characterizing different excitations of the charge-density wave.
