Spatiotemporal mode-locking in multimode fiber lasers: towards spatiotemporal dissipative solitons.

Optical solitons forming in fiber resonators feature properties that hinge on the system parameters, such as dispersion, nonlinearity, gain, and loss. This work demonstrates the heteronuclear multicolor soliton compounds composed of chirp-free conventional solitons and chirped dissipative solitons, by introducing convex-concave frequency phases in mode-locked fiber lasers.

Nonlinear optical effects are by default weak but they can be enhanced by sculpting the resulting spectrally periodic pulses from a fibre laser into an optimal shape.
