摘要：

The optical reflectivity as a function of temperature of the title compounds has been measured over a broad spectral range from 4 meV up to 12 eV. On the one hand, our findings suggest a very anisotropic dynamics of the charge excitation spectrum when measuring along or perpendicular to the ladders in Sr14-xCaxCu24O41. On the other hand, the investigation of Sr0.73CuO2 allows us to study the electrodynamics of hole doped CuO2 chains alone without complications arising from the presence of Cu2O3 ladders in Sr14-xCaxCu24O41.
