Radiation induced complexes in low carbon concentration, low electron dose Czochralski silicon crystal are examined by infrared absorption spectroscopy. By using the highly sensitive, highly accurate measurement and arithmetic procedures, carbon-oxyg

We show that the quantum Stokes parameters aptly describe the nonclassical two-polarization-mode Fock states and the transformation of their polarization states. In this description, the two-polarization-mode Fock states are the simultaneous eigensta

We investigated the population transfer of Ar 1s5 metastable atoms under optical pumping of the 1s5–2p9 transition in an Ar–He glow discharge. From the pump-probe experiment, we found that the population density of the 1s5 level was decreased. We

We applied the cross-correlation analysis to the resonant Voigt-effect spectroscopy of the magnetic field-induced transition in the oxygen A band b1 Σ g+ ( v' = 0)– X3 Σ g− ( v = 0). By calculating the cross-correlation function of the experime

We developed a technique for the high-sensitivity detection of the magnetically induced birefringence of gases. Elliptically polarized light from a GaAlAs diode laser was used to probe the change in ellipticity caused by the presence of oxygen gas in

The light-ellipticity change ψ caused by the off-resonant magnetic birefringence of gases (O2, N2, Ar) wasmeasured with a high-sensitivity polarimeter. In order to reduce background noise, we improvedthe extinctionratio of the polarimeter by using h

We investigated the magnetic-field-induced transition of the oxygen molecule in the region of the forbidden electronic band b 1 Σ g + (v′ = 0)–X 3 Σ g − (v = 0). To detect the induced transition we used the resonant Voigt effect (magneto-opti

We investigated the resonant magneto-optic spectra of the electronic band b 1 Σ + g – X 3 Σ − g of the oxygen molecule. The theoretical analysis was made on the basis of the Zeeman effect of the magnetic-dipole transition. The oxygen molecules

The atmospheric oxygen band, b1Σ+g (υ'=0)-X3Σ-g (υ″=0), was detected by the resonant Voigt-effect (optical anisotropy induced in a transverse magnetic field), using a titaniumdoped sapphire laser as a light source. Elliptically polarized light

The excited-state atom densities in the negative glow of a direct-current glow discharge are derived from the spectral-line intensity of radiative atoms and the resonance-fluorescence photon flux of nonradiative atoms. The discharge is operated in a
