Acquisition of gated spectra from white-light continuum using ultrafast Kerr gate of SrTiO3 crystal

摘要：

We investigated the optical Kerr effect of SrTiO3 (STO) crystal, which showed an ultrafast response of less than 200 fs and a large nonlinear refractive index of 1.97×10-15 cm2/W. Using optical Kerr gate (OKG) technique with a STO crystal, we obtained narrow-bandwidth and symmetric gated spectra from the white-light continuum generated in water with a femtosecond laser. The experimental results showed more superiority comparing with the gated spectra obtained by OKG with CS2 as Kerr medium.
