Abstract
We demonstrated pulse compression at 1 μm based on the use of microstructured optical fibers. Two different approaches have been investigated. On the first hand, we used fibers with negative group velocity dispersion at the laser emission to obtain self-compression based on solitonic effect. On the second hand, we used fibers with zero-dispersion at the laser emission to generate very broad spectra (by self-phase modulation) recompressed afterward using prism-based compressor. We studied experimentally and theoretically these two techniques of compression with a special care regarding their limitations. For the experiments, the compressions have been obtained using a home-made diode-pumped Yb:SYS laser producing 110-fs pulses directly injected in the microstructured optical fibers. We demonstrated compressed pulses as short as 20-fs centered at 1070 nm which is to our best knowledge the shortest pulses obtained with a diode-pumped system in this wavelength range.
