Abstract

The nonlinear refraction of chlorophosphonazo I (CPA I) was investigated using the Z-scan technique with a pulse Nd:YAG laser and a cw He{single bond}Ne laser as excitation sources. Positive and large nonlinear refractive index attributed to resonant electronic nonlinear effect was observed under pulse 532 nm excitation. Under cw He{single bond}Ne 633 nm excitation, the origin of optical nonlinearity was discussed in term of laser heating effect. The experimental results show that CPA I will have potential applications in nonlinear optical devices.
