FIG. 1.

(Color online) Room-temperature absorption spectrum of samples E1000 (squares) for - and -polarized light and E900 (circles) for -polarized light at Brewster’s angle of incidence. The inset shows the absorption for -polarized light of samples E1000 (squares) and E900 (circles) measured in a multipass waveguide.
