Abstract:	Thin films of (Pb1−xSrx )TiO3, x = 0, 0.5, 1.0 have been prepared on glass substrates by the chemical solution method using the spin-coating technique. The optical nonlinearity in the visible spectral region is investigated using short (5 ns) laser pulses at the off-resonant wavelength of 532 nm employing the open aperture z-scan technique. It is found that the third order nonlinear absorption is dependent on the lead content of the films, with the compositions x = 0, 0.5 exhibiting large values (β ∼ 10−7 m/W), thereby suggesting the possible use of these materials as optical limiters. No optical nonlinearity is observed for the composition with x = 1.0.
