The thermal third order nonlinearity of a neutral density glass is measured using the Z-Scan method. The measurements are performed using two different laser configurations: a continuous wave laser at 532 nm and a femtosecond laser at 1060 nm. The measurements are used to determine the nonlinear refractive index, n 2 and the thermo-optical coefficient dt dn of the samples. The measurements in the two different laser configurations are in good agreement with the existing theory models.

Abstract
The thermal third order nonlinearity of a neutral density glass is measured using the Z-Scan method. The measurements are performed using two different laser configurations: a continuous wave laser at 532 nm and a femtosecond laser at 1060 nm. The measurements are used to determine the nonlinear refractive index, n 2 and the thermo-optical coefficient dt dn of the samples. The measurements in the two different laser configurations are in good agreement with the existing theory models.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
