摘要：

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/cm(2). Photodarkening was observed when intensities larger than approximate to200 MW/cm(2) were incident on the samples. (C) 2002 American Institute of Physics.
