The effect of laser irradiation on photodarkened CdS-doped glass has been investigated as a function of the wavelength of laser light, using electron spin resonance (ESR) and time-resolved luminescence. When the wavelength of laser light is tuned to 500 nm, the intensity of the ESR signal associated with photodarkening decreases, as does the decay rate of luminescence. This indicates laser-induced reversion of photodarkening.
