Ultrafast fiber lasers based on self-similar pulse evolution: a review of current progress
We summarize the state of research on lasers based on self-similar pulse evolutions, including passive similariton, amplifier similariton, and others. Self-similar fiber lasers are conceptually different from other kinds of short-pulse lasers. This distinction allows for exciting new laser design options.
Characteristic steady-state round trip evolutions of the pulse chirp for different mode-locking regimes. Solid lines indicate the chirp of the pulse, while dashed lines indicate the local dispersion of the cavity. In the highlighted plot, the lines show the difference of the pulse from a parabolic pulse.
