Optical absorptions have been measured in chalcopyrite, CuFeS_2, and Fe-doped CuAlS_2 and CuGaS_2. An extra absorption band with two peaks is observed at the low energy region of the absorption edge for Fe-doped CuAlS_2 and CuGaS_2.Energy positions of two absorption peaks are 1.3 eV and 2.0 eV for CuAlS_2 and 1.2 eV and 1.9 eV for CuGaS_2, respectively. The intensity of this absorption band increases with the increase of doped Fe ions and grows into the absorption edge of CuFeS_2. Its oscillator strength comes up to 7・10^<-2>. In chalcopyrite photoconductivity is observed and its maximum is just at the same energy region of the absorption edge. By comparing our results with those of absorption measurements for Cu- or Fe-doped ZnS it is concluded that this absorption band originates from the charge transfer transitions relating to 3d electron of Fe ions and the absorption edge of CuFeS_2 rises from the band-to-band transition corresponding to this charge transfer transition.
