    • Cooperative recombination of electron-hole pairs in semiconductor quantum wells under quantizing magnetic fields 
      Jho, Y. D.; Wang, X.; Reitze, D. H.; Kono, J.; Belyanin, Alexey; Kocharovsky, V. V.; Kocharovsky, Vl V.; Solomon, G. S. (American Physical Society, 2010)
      We present results of detailed investigations of light emission from semiconductor multiple quantum wells at low temperatures and high magnetic fields excited by intense femtosecond laser pulses. The intensity and linewidth ...
    • Electromagnetically induced transparency in rubidium vapor prepared by a comb of short optical pulses 
      Sautenkov, V. A.; Rostovtsev, Y. V.; Ye, C. Y.; Welch, George R.; Kocharovskaya, O.; Scully, Marlan O. (American Physical Society, 2005)
      It was shown by Kocharovskaya and Khanin [Sov. Phys. JETP 63, 945 (1986)] that a comb of optical pulses can induce a ground-state atomic coherence and change the optical response of an atomic medium. In our experiment, we ...
    • Inversionless lasing with self-generated driving field 
      Belyanin, Alexey; Bentley, C.; Capasso, F.; Kocharovskaya, O.; Scully, Marlan O. (American Physical Society, 2001)
      We propose and study resonant ladder schemes of inversionless lasing on a fast-decaying transition when the population inversion is not possible or Very difficult to achieve. The driving field on a neighboring, slowly ...
    • Ionization by few-cycle pulses: Tracing the electron orbits RID A-7617-2010 
      Milosevic, D. B.; Paulus, Gerhard G.; Becker, W. (American Physical Society, 2005)
      High-order above-threshold ionization by few-cycle laser pulses is analyzed in terms of quantum orbits. For a given carrier-envelope phase, the number of contributing orbits and their ionization and rescattering times ...
