We have measured the optical conductivity of K 0.3MoO 3 both above and below the charge density wave transition. We find clear evidence for a collective mode contribution to the optical conductivity $\sigma(\omega)$ and for a gradual opening of a pseudogap at temperatures above the charge density wave transition, but below the mean field transition temperature. We also discuss the parameters which characterize the electrodynamic response in the fluctuation regime.
