| Abstract: | We investigate the spectrally resolved transient reflectivity changes Delta R(T,tau,lambda) in the charge density wave (CDW) conductor o-TaS3. A distinct near-infrared resonance in this compound emphasizes the characteristic Delta R(lambda) resonances, and allows a selection of coexisting CDW phases with different nonequilibrium carrier dynamics. Furthermore, the spectrally resolved Delta R(tau) characterizes the collective oscillations associated with the individual states. We believe that this demonstration paves the way for the optical selection of the multiphase order that plays an important role in various macroscopic quantum systems. |
