摘要：

We report the results of the c-axis infrared spectroscopy of La2-xSrxCuO4 in high magnetic field oriented parallel to the CuO2 planes. A significant suppression of the superfluid density with magnetic field rho(s)(H) is observe for both underdoped (x = 0.125) and over ope (x = 0.17) samples. We show that the existing theoretical models of the Josephson vortex state fail to consistently describe the observe effects and discuss possible reasons for the discrepancies.
