Accurately characterizing the field of broadband optical pulses is required for developing
new optical sources, performing successful experiments, and interpreting experimental …

The use of structured ultrashort pulses with coupled spatiotemporal properties is emerging
as a key tool for ultrafast manipulation. Ultrafast vector beams are opening exciting …

We report on a programmable liquid crystal spatial light modulator enabling independent
orbital angular momentum state control on multiple spectral channels. This is done by using …

Guided wave optics, including most prominently fiber optics and integrated photonics, very
often considers only one or very few spatial modes of the waveguides. Despite being known …

Special light beams are becoming more and more interesting due to their applications in
particle manipulation, micromachining, telecommunications or light matter-interaction. Both …

Based on the exact solution of the Maxwell equations in the form of a collapsing spherical
vector wave specified by an arbitrary function of time, we have calculated the maximum …

We propose a simple formulation for the baseline design of a hybrid lens, consisting of
refractive and diffractive elements, intended for focusing ultrashort laser pulses. Lens …

Ultrashort laser pulses are described as having chromatic astigmatism, where the astigmatic
phase varies linearly with the offset from the central frequency. Such a spatio-temporal …

With the rapid development of ultra-intense femtosecond lasers, the measurement and then
the improvement of the temporal contrast (ratio of signal to noise) become more and more …

The output power of the fiber laser can be increased by synthesizing the output beam, but
the problem of low output power is caused by the poor ability of controlling bandwidth in the …
