Tunable ultrafast infrared generation in a gas-filled hollow-core capillary by a four-wave mixing process
Abstract
In this paper, we numerically and experimentally investigate the
four-wave mixing process in a gas-filled hollow-core capillary in
the femtosecond regime. The interaction between a visible broadband
continuum and a chirped pump pulse resulted in the generation of a
tunable near-infrared pulse of 1.2 to 1.5 µm and with the
potential to reach the midinfrared range. Numerical simulations
were performed in order to fully understand the role of key
parameters such as the gas pressure, chirps, and relative delays of
the involved pulses. The experimentation, which demonstrated and
highlighted the feasibility of the tunable femtosecond source, led
to the generation of an idler at 1.2 µm with a duration of
