Nonlinear optical absorption of antimony and lead oxyhalide glasses

Nonlinear optical properties and optical limiting behavior of antimony and lead oxyhalide glasses were studied using laser pulses of 80 ps at 532 nm. The standard Z-scan technique was used to determine large nonlinear absorption coefficients which range from 11 to 20 cm/GW, using intensities of 100...

Description
Summary:Nonlinear optical properties and optical limiting behavior of antimony and lead oxyhalide glasses were studied using laser pulses of 80 ps at 532 nm. The standard Z-scan technique was used to determine large nonlinear absorption coefficients which range from 11 to 20 cm/GW, using intensities of 100 MW/cm2. Photodarkening was observed when intensities larger than ≈200 MW/cm2 were incident on the samples.
