摘要：

The nonlinear refractive-index (n2) spectrum of ZnSe near the band gap (lambda-gap approximately 450 nm) at 77 K was measured for the first time to our knowledge by using self-bending of a pulsed laser beam. The maximum nonlinearity, n2 approximately 1.9 x 10(-8)cm2/W, measured by us is anomalously large, which cannot be explained by conventional thermally induced band-gap shrinkage.
