Transient photodarkening induced by a nanosecond pulsed laser in amorphous and liquid As2Se3: fractal characteristics in relaxation dynamics
Both amorphous and liquid As 2 Se 3 exhibit fast decrease of optical transmittance under a nanosecond pulsed laser excitation. This light-induced effect is called fast photodarkening (PD). After the cessation of excitation (one shot), the PD recovers within 0.1 s, but remains in a wide time domain f...
