Interferometric autocorrelation measurements of ultrafast two-photon nonlinearities in CdSe

Bulk crystals of CdSe are studied to verify it as an alternative to AlGaAs in the 1.5 μm wavelength due to its half-gap energy of 0.875 eV and large nonlinear figure of merit. The pulses transmitted to the crystal are characterized by interferometric autocorrelation and spectral analysis. Detailed n...

description Bulk crystals of CdSe are studied to verify it as an alternative to AlGaAs in the 1.5 μm wavelength due to its half-gap energy of 0.875 eV and large nonlinear figure of merit. The pulses transmitted to the crystal are characterized by interferometric autocorrelation and spectral analysis. Detailed numerical modeling are used to identify the contributions of the different effects. Femtosecond pulses from an optical parametric oscillator, operating between 1.4 and 1.6 μm, are used. The nonlinear refractive index of 1.3×10-13 cm2/W compares favorably to AlGaAs and is suitable for a number of nonlinear applications.
