Abstract

Photonic-crystal fibers are employed to demonstrate widely tunable frequency down-conversion of unamplified 6fs Ti:sapphire laser pulses through the soliton self-frequency shift induced by the Raman effect. Wavelength shifts as large as 500nm are achieved for input few-cycle pulses with broadband spectra centered at approximately 820nm. The central wavelength of the redshifted output of a photonic-crystal fiber is smoothly tuned from the low-frequency edge in the spectrum of the 6fs Ti:sapphire laser pulse up to 1.35μm by varying the input energy in the fundamental mode of the fiber.
