We report the generation of multimode solitons in step-index fibers. The solitons are superpositions of 5–10 temporally aligned transverse modes, they exhibit speckled beam profiles, and the spatio-spectral variation across the soliton can be compl

Mode-locking refers to the generation of ultrashort optical pulses in laser systems. A comprehensive study of achieving high-energy pulses in a ring cavity fiber laser that is passively mode-locked by a series of waveplates and a polarizer is present

Many new applications for electron accelerators require high-brightness, high-average power beams, and most rely on photocathode-based electron injectors as a source of electrons. To achieve such a photoinjector, one requires both a high-power laser

Minimizing the electron-beam emittance of photoinjectors is an important task for maximizing the brightness of the next-generation x-ray facilities, such as free-electron lasers and energy recovery linacs. Optimally shaped laser pulses can significan

To achieve the lowest emittance electron bunches from photoemission electron guns, it is essential to limit the uncorrelated emittance growth due to space charge forces acting on the bunch in the vicinity of the photocathode through appropriate tempo

Spatiotemporal mode-locking in a laser with anomalous dispersion is observed. Experimental results are compared to numerical simulation, which show strong temporal breathing.
