Figure 1.

The schematic diagram of the experimental geometries and the spectra of the normalized CPGE current. The schematic diagram for geometries CPGE-I (a) and CPGE-II (b and c). The spectra of the normalized CPGE current obtained by geometry CPGE-II at different angles of incidence (d). The thin lines indicate the sum of jR and jD by the geometry shown in (b), and the thick lines indicate the difference of jR and jD obtained by the geometry shown in (c). All of the spectra are shifted vertically for clarity.
