title: Spectral compression of frequency-shifting solitons in a photonic-crystal fiber.
abstract: A highly nonlinear photonic-crystal fiber is used to demonstrate spectral compression of femtosecond light pulses combined with a tunable soliton frequency shift. A spectral compression ratio of 6.5 is achieved for solitons produced by unamplified 50 fs 1270 nm Cr:forsterite laser pulses shifted by the Raman effect to a central wavelength of 1.58 microm.
