25.5 fs dissipative soliton diamond Raman laser.

We have demonstrated a dissipative soliton diamond Raman laser that generates 25.5 fs pulses. Synchronously pumped by a 128 fs Ti:sapphire laser, the Raman cavity employed a pair of chirped mirrors to optimize the group delay dispersion, resulting in a Stokes field with 125 nm of spectral bandwidth from 840 to 965 nm. The Stokes pulse formation can be described as a dissipative soliton balancing self-phase modulation, normal dispersion, and gain due to stimulated Raman scattering (SRS).
