Characteristic Maximum

The spectral and nonlinear optical properties of InAs nanowires suspensions in isopropanol were studied at room temperature. InAs nanowires were synthesized by molecular beam epitaxy. The absorption spectra of suspensions with a characteristic maximum at a wavelength of 235 nm were obtained, as well as Raman spectra in the range 180–280 cm – 1. The nonlinear transmission of InAs nanowires with a diameter less than the Bohr radius of the exciton upon two-photon excitation in the transparency region in the visible range (λ = 468 nm) was studied firstly. The effect of cumulative bleaching was discovered, the manifestation of which is associated with the dynamic Stark effect.

Photon Resonance

We consider the interference spectra arising from the competition between a spontaneous process and two processes induced by two laser fields, which are coupled with a three-level atom in the "Λ" configuration. In the low-intensity limit of both laser fields and on two-photon resonance, the frequency profiles of the two peaks, which arise from the spontaneous and induced processes, cancel each other out completely at the center of the line for zero detuning and at the finite values of the detuning as well. At high intensities of the laser fields and on two-photon resonance, the dynamic Stark effect dominates the spectra of the excited state of the atom. Expressions for the interference spectra and correlation functions are derived, which describe the physical process of the absorption of a laser photon at two different times by the ground state of the atom. Interference spectra and correlation functions are calculated for the two-photon off-resonance and for the proces of the absorption of a photon by the ground state of the atom. In this case, the intensities of the frequency dips take negative values indicating that stimulated emission prevails for certain values of the detunings. Using values for the parameters involved close to those for Ba+, the computed two-photon resonance and off-resonance spectra are graphically presented and discussed.
