Abstract :
Doubly phase-matched cascaded four-wave mixing in tapered fibers is demonstrated using femtosecond Cr:forsterite laser pulses. The first stage of this cascade involves phase-matched third-harmonic generation. At the second stage, the third harmonic and fundamental radiation generate new spectral components through phase-matched parametric wave mixing.
