Stretched Pulse Image

Caption

In the stretched-pulse soliton Kerr resonator developed by the lab of William Renninger, a single frequency laser enters a fiber ring cavity, generating a broad bandwidth comb of frequencies at the output that supports ultrashort femtosecond pulses. Inside the fiber cavity the pulses stretch and compress in time, reaching a minimum duration twice in the cavity near the center of each of the two fiber sections. The stretching and compressing temporal evolution is a salient characteristic of femtosecond stretched-pulse soliton Kerr resonators.
