| Popis: | z-scan experiments and beam propagation modeling were conducted to determine the nonlinear absorption and refractive index cross sections of n-type indium arsenide (InAs). A doubled carbon dioxide pulsed laser operating at 4.78μm was used to generate free carriers via two-photon absorption. Using published values for the two-photon absorption coefficient in InAs, a nonlinear beam propagation model and a data fitting routine were used to extract the nonlinear absorption and refractive index cross sections. |
