Generation of periodic sequences of compressed pulsed using the ultrafast molecular modulator

Summary form only given.In the recent years, the traditional technique of fs-pulse generation based We present the first results on compression of the output pulses transmitted through impulsively excited SF/sub 6/ and exhibiting side-band Raman spectra. In our experiments we used a Ti:sapphire chirped pulse amplification laser system at 1 kHz repetition rate. The output pulses at 800 nm had an energy up to 500 /spl mu/J and a pulse width of 25 fs and could impulsively excite the symmetric vibrational mode of SF/sub /6.
