Convolution theorem for nonlinear optics

The convolution theorem for nonlinear optics

We have expressed the nonlinear optical absorption of a semiconductor in terms of its linear spectrum. We determined that the two-photon absorption coefficient in a strong DCelectric field of a direct gap semiconductor can be expressed as the product of a differential operator times the convolution integral of the linear absorption without a DC-electric field and an Airy function. We have appli...

Synthesis of TiO2-ZnO-ZrO2 Nanocomposites for Nonlinear Optics Applications

A sol-gel technique under ultrasonic irradiation was applied to synthesize ZrO2/TiO2/ZnOnanocomposites. X-ray diffraction analysis confirmed the successful synthesis of nanocomposites. The strain and crystalline size values of ZrO2/TiO2/ZnO nanocomposites are estimated to be 9.98×10-4 and 17.66 nm, respectively. The linear absorption coefficient of ZrO2/TiO2/ZnO nanocomposites was measure...
