Abstract
We demonstrate soliton self-frequency shift of more than 12% of the optical frequency in a higher-order mode solid, silica-based fiber below . This new class of fiber shows great promise for supporting Raman-shifted solitons below in intermediate energy regimes of 1 to that cannot be reached by index-guided photonic crystal fibers or air-core photonic bandgap fibers. By changing the input pulse energy of pulses from 1.36 to we observe Raman-shifted solitons between 1064 and with up to 57% power conversion efficiency and compressed output pulse widths less than . Furthermore, due to the dispersion characteristics of the HOM fiber, we observe redshifted Čerenkov radiation in the normal dispersion regime for appropriately energetic input pulses.
