Nonlinear Optical Properties of the “Green” Liquid Laser Medium
Using Nd2O3 and HCl as raw materials, Nd (phen)2Cl3 was obtained and its spectral characteristics were measured. With Nd2O3, benzoic acid and ophenanthroline as the raw material, green liquid laser medium Nd3+ ions complexes—NdB3phen (tribenzoic acidphenanthroline coNd) was prepared. The thirdorder nonlinear optical properties of NdB3phen were studied using femtosecond laser and signalbeam Zscan method. When the incident femtosecond laser pulse wavelength is 400 nm, the peak power density is 2.94×1014 W/m2, and pulse width is 117 fs, the measured nonlinear refractiveindex coefficient of the sample is -2.84×10-15 cm2/W. Under the opening aperture configuration, NdB3phen presents phenomenon of the reverse saturated absorption, and the measured twophoton absorption coefficient is estimated to be 9.11×10-12 m/W. The experimental results show that twophoton absorption coefficient and nonlinear refractiveindex coefficient of NdB3phen refractive index become more intense.
