Abstract
We present new data on the c-axis far infrared reflection spectrum of La1.85Sr0.15CuO4. The observed reflectance edge below T-c is interpret ed in a Josephson plasma oscillation model, which provides a novel spe ctroscopic way to determine the critical current density. Furthermore, we show that the presence of a small absorption peak near the aero cr ossing of the dielectric function can be explained in an effective med ium calculation.
