We present an infrared spectroscopy study of charge dynamics in CaCo_2As_2 single crystal. In this material, the optical conductivity can be described by two Drude components with different scattering rates（1/τ）： a broad incoherent background and a narrow Drude component. By monitoring the temperatu...
