We have investigated the photoinduced anisotropy in chalcogenide $As_{40}Ge_{10}Se_{15}S_{35}$ thin films, non-doped and photodoped by Ag and Cu. The films were exposed by the linearly polarized He-Ne laser light( $\lambda$=632.8nm). The Ag and Cu photodoping resulted in reducing the time of saturation photoinduced linearly dichroism. Also photoinduced linearly dichroism was increased up to maximum 184% by Ag photodoping and 138% by Cu photodoping, respectively. As the result of this study, the linearly dichroism can be interesting for different applications of photoinduced anisotropy. In addition, it will offer lots of information for the photodoping mechanism and analysis of chalcogenide thin film.
