Kinetics of laser-induced photodarkening in arsenic based chalcogenide glasses
Original language description
Photoinduced changes in the optical properties of chalcogenide glass thin films have been studied extensively but usually only permanent changes were recorded through measurements before and after exposure to pump light. To understand the progression ofsuch effects, in this paper we report in situ measurement of transient changes in the optical transmission of amorphous As(2)Se(3), As(5)Se(5) and As(4)Se(3) thin films during their exposure to a He-Ne laser which has photon energy close to the bandgap of the studied compositions. Mathematical expressions are established, which describe accurately both the light intensity and time dependences of photodarkening. The structural origin of the observed changes is discussed briefly.
