The propagation of high-peak-power (> 10-kW) sub-100-fs pulses near the zero-dispersion
wavelength of an optical fiber was studied experimentally. Four-photon mixing and …

Nonlinear propagation of high-power femtosecond pulses close to the zero-dispersion
wavelength of a single-mode optical fiber is studied experimentally and numerically. The …

We demonstrate experimentally and theoretically that frequency-modulated femtosecond
laser pulses can be spectrally narrowed by self-phase modulation in optical fibers. We …

We propose and demonstrate a pulse compression technique using a hollow fiber with a
pressure gradient. This technique improves the spatial and spectral qualities of femtosecond …

We present a high-average-power femtosecond laser system at 520nm central wavelength.
The laser system delivers sub-500fs pulses with 135W average power at a pulse repetition …

The quest for the world's shor test laser pulse has led to a re markable pace of develop ment
in ultrafast laser technology. Al though pulses of only a few cycles duration have been made …

We have developed a beam stabilization system for high-power femtosecond lasers
operating at a repetition rate of 1 kHz⁠. The beam pointing at a hollow fiber input was …

The optical pulse evolution in a highly nonlinear normal dispersion-increasing fiber has
been considered, both experimentally and theoretically. It was found that large spectral …

We report a strong spectral broadening of femtosecond pulses propagating in a single-mode
As-S glass fiber of 1.5 m length. The pump pulse spectrum is broadened by a factor of five …

A series of experiments aimed at determining the maximum pulse energy that can be
produced by a femtosecond fiber laser is reported. Exploiting modes of pulse propagation …
