摘要：
In the present work, third-order nonlinear optical parameters of lithium potassium borate (LiKB4O7) crystal, a potential NLO material, are determined along the three crystallographic axes using Z-scan technique. The high value of nonlinear refractive index (n2) obtained along c-axis is −7.582 × 10−11 cm2/W, and the corresponding third-order nonlinear susceptibility (χ3) is 4.858 × 10−9 esu. The measured nonlinear refractive indices reveal the self-defocusing effect of LiKB4O7 crystals.
