Observation of picosecond UV pulses produced by coherent scattering of IR femtosecond pulses in atomic rubidium vapor Academic Article uri icon


  • We report the observation of coherent UV light pulses by the coherent scattering of IR pulses from atomic rubidium vapor. Rubidium atoms were first excited by a 100 fs pulse from the 5S ground state to the 5D state via a two-photon transition. The atoms were then pumped by an IR pulse resonant to the 5D-12P transition. The presence of the IR pulse triggered the instantaneous emission of a UV light pulse on the 12P-5S transition. The pulse had a time duration of tens of picoseconds, which was measured by a picosecond-resolution streak camera. The temporal shape of the generated light is explained by a simplified atom-field interaction theory. 2011 Optical Society of America.
