Generation of sub-100-fs pulses from a microstructure-fiber-based optical parametric oscillator.
We report on the generation of 70-fs pulses at a center wavelength of 880 nm using a microstructure-fiber-based optical parametric oscillator pumped by a fiber laser operating at 1032 nm. We present optical spectra and autocorrelation measurements that illustrate the generation of ultrashort pulses and the onset of saturation at sufficiently high pump powers. Generation of ultrafast pulses with nanojoule energies provides new opportunities for extending the functionality of mode-locked fiber lasers.
