Soliton modelocking with normal dispersion via adiabatic excitation of χ(2) solitons in apodized fanout PPLN devices

摘要

We demonstrate soliton modelocking of a Yb:CALGO laser via cascaded second-order nonlinearities whereby the second-harmonic is adiabatically excited/de-excited in an apodized-fanout-PPLN crystal. We obtain 100-fs pulses at 540 MHz with 760 mW average power.
