Abstract: | Previous studies of the spectral response of p-Ge photon drag and n-Gap photon drag-optical rectification detectors have been extended. Measurements have also been made of the spectral response of p-Si photon drag, p-GaP photon drag-optical rectification and p-GaAs photon drag-optical rectification detectors. The wavelength range of main interest is between 2 and 11 μm, (HF, HCl, HBr, H2O vapour and CO2 lasers), but some measurements have also been made at 28 and 33 μm, (H2O vapour laser). |
