摘要：
The third-order nonlinear optical response of molybdenum disulfide dissolved in ethanol was investigated using a modified time-resolved pumpeprobe measurement with phase object at 532 nm with pico-second laser pulse. The experimental results clearly indicate that the observed nonlinear response should be of excited-state origin. The compound exhibits strong saturable absorption and long excited-state lifetimes. The nonlinear absorptive and refractive parameters of the phenoxazinium salt were evaluated by combination of picosecond pumpeprobe measurements and picosecond Z-Scan experiments. The experiment results demonstrate this compound is a promising nonlinear optical material.
