Optical amplification in the near-infrared in gas-filled hollow-core fibers.
We demonstrate efficient optical parametric amplification and generation in a gas-filled hollow-core fiber of near-infrared pulses, peaked at 1.4 microm wavelength, with 5 microJ energy and 45 fs duration at the fiber output. Numerical simulations confirm that the OPA is phase matched through excitation of higher-order fiber modes.
