Nonlinearity and photostructural changes in glassy As sub 2 S sub 3 thin films

Nonlinearity and photostructural changes in glassy As sub 2 S sub 3 thin films

Two contributions to refractive index changes are demonstrated. Permanent change is demonstrated under normal incidence transmittance measurements. Dynamic change is revealed by Z-scan technique; it disappears once the light source is turned off.
