要旨:
Transient stimulated Raman scattering is investigated in methane-filled hollow-core photonic crystal fiber. Using frequency-chirped ps-pulses at 1.06 mu m as pump and tunable CW-radiation as Stokes seed, the vibrational excitation of the CH4 molecules can be controlled on the sub T-2 time-scale. In this way the generated Stokes pulse can be phase-locked to the pump pulse and its spectrum manipulated. (c) 2009 Optical Society of America
