Coherence as ultrashort pulse train generator

Intense, well-controlled regular light pulse trains start to play a crucial role in many fields of physics. We theoretically demonstrate a very simple and robust technique for generating such periodic ultrashort pulses from a continuous probe wave which propagates in a dispersive thermal gas media.     

Polymeric dressing formulations containing water-soluble fullerene derivatives

The effect of small additions of water-soluble fullerene C₆₀ derivatives on the strength properties of polyvinyl alcohol films was examined. Solutions of polyvinyl alcohol and fullerenol were tested as polymeric dressing formulations for glass-reinforced plastics based on a thermoplastic polyethylene or polyamide matrix.     

Laser Running Waves for the Kapitza–Dirac Diffraction in the Atom Interferometer

The scheme of multi-momentum atom interferometer based on the resonant Kapitza–Dirac diffraction is considered. The conclusion is made that the arms of counter propagating waves forming the standing wave, which scatters the atoms, should have the equal length.
