    Josephson dynamics for coupled polariton modes under the atom–field interaction in the cavity

    We consider a new approach to the problem of Bose–Einstein condensation (BEC) of polaritons for atom–field interaction under the strong coupling regime in the cavity. We investigate the dynamics of two macrosc...

    Two-octave spectral broadening of subnanojoule Cr:forsterite femtosecond laser pulses in tapered fibers

    Spectral broadening of femtosecond Cr:forsterite laser pulses is enhanced due to the use of tapered fibers. Supercontinuum generation with unamplified subnanojoule femtosecond Cr:forsterite laser pulses is obs...

    Superhigh resolution spectroscopy in methane with cold molecules

    Use of optical selection of cold particles in saturated absorption spectroscopy is discussed. Owing to this we observed directly the splitting of a methane absorption line (λ=3.39 μm) due to recoil effect in a...
