摘要：
This research experimentally investigates the nonlinear absorption and refraction in promising nonlinear crystals, sulfur-containing and selenium-containing barium chalcogenides by the single-beam Z-scan technique. A nanosecond Nd: YLF laser operating at 1.053 mu m was used as the radiation source. The experimental data are compared with values obtained from theoretical models. The obtained results demonstrate significant agreement with the predicted ones.
