The technique of Second-Harmonic Generation (SHG) of CO~2~ laser for carbon monoxide concentration detection is investigated in this paper. A simple mechanical Q-switched CO~2~ laser is used in our experiment, which works at 9.586 ΞΌm. The nonlinear optical crystal used for frequency doubling is ZnGe

We apply a microscopic formulation to calculate the second harmonic spectra of Si(100) 2 Γ 1. We compare the calculated second harmonic radiated efficiency for several 2 Γ 1 reconstructions, with different dimer bucklings, with each other. Besides the surface-allowed E 1 , E 2 andE H 1 resonances, o
## Abstract A timeβdomain nonlinear model representing the propagation of ultraβshort optical pulses in dispersive materials containing second order nonlinearity is presented. The model accounts for material dispersion through Lorentz model in addition to the spatiotemporal coupling between the pul
We observed an in situ process of ozone adsorption on Si(111)7 Γ 7 at di β erent temperatures by second harmonic generation (SHG). On ozone exposure, the second harmonics (SH) intensity descreased close to a detectable limit on the surface at room temperature (RT). However, we observed the appearance
