DOI: 10.1007/s10946-017-9644-6
Abstract: Based on a modified cross-correlation technique, we experimentally demonstrate a technique for measuring the spatial–temporal intensity of laser pulses. Pulse widths at different spatial positions of the ultrashort pulse are measured by changing the scan… read more here.

DOI: 10.1109/jlt.2022.3152154
Abstract: We demonstrate experimentally that random phase modulation of an erbium-doped fiber ring-laser by an intra-cavity electro-optic phase modulator did not inhibit ultra-short pulse operation (so-called mode-locking). Stable and self-starting operation was achieved even when the… read more here.
