Short pulse generation due to coherent population trapping Conference Paper uri icon

abstract

  • An efficient broadband optical continua generation due to stimulated Raman scattering originated from relaxation processes from the excited electronic states is predicted. It is shown that, even when the populations of Raman levels are equal, Raman coherence can be efficiently excited due to coherent population trapping process (CPT). Scattering of the electromagnetic field due to the excited coherence gives rise to a comb of equally spaced spectral components of optical radiation. The generated spectrum can be compressed into a sequence of ultrashort pulses. Estimates for realistic parameters of the medium show that it is possible to produce a sequence of femtosecond and even subfemtosecond pulses with repetition rate several GHz.
