Abstract
Nonlinear absorption of carbon disulfide was studied in the wavelength region of by using Z-scan method with nanosecond pulses. Large nonlinear absorption was found in the short-wavelength region . The optical limiting properties of were also studied, and results showed that has good optical limiting capability in the region. The mechanism of the nonlinear absorption was analyzed by the temporal profile of pulses going through . The large nonlinear absorption is believed to arise from a combination of two-photon absorption and the excited-state absorption induced by two-photon absorption.
