利用200-fs脉冲激光源，采用瞬态四波混频技术测量了层状钙钛矿型材料（C6H13NH3）(2)PbI4的三阶非线性光学磁化率chi((3))（-omega; omega, -omega, omega）。在8k的最低激子共振下，最大\chi((3))\值为1.6 x 10(-6) esu。激子的纵向弛豫时间为7 ps，横向弛豫时间为0.2 ps。1998爱思唯尔科学有限公司
The third-order nonlinear optical susceptibility, chi((3))(-omega; omega, -omega, omega), of the layered perovskite-type material (C6H13NH3)(2)PbI4 is measured by a transient four-wave mixing technique using a 200-fs-pulse laser source. The maximum \chi((3))\ value is 1.6 x 10(-6) esu at the lowest-exciton resonance at 8 K. Longitudinal and transverse relaxation times of the excitons are 7 ps and 0.2 ps, respectively.
