Some of our teammates will visit CLEO in Munich, you'll be able to meet them
during their talks and poster sessions. See the list of contributions
related to our group at the bottom of this page.
Tomasz Kardaś will talk on novel approach towards noncollinear pulse propagation.
The video on the right shows sample simulation of broadband noncollinear sum frequency generation in BBO, the interacting pulses
are travelling at a mutual angle of 26°
Paweł Wnuk will talk on Multi-harmonic generator and synthesizer. The small contributions
from our group in this subject was the customization of the Hussar script used for simulations in the design phase.
Jan Szczepanek will present his poster on nonlinear polarization evolution in polarization-maintaining fibers.
You can reed more on this subject in our recent paper in Optics Letters
and on our page.
Piotr Kabaciński will show his poster on n2 measurement through analysis of FROG
maps of the pulses subjected to nonlinear propagation through various media: fused
silica, calcite and YVO4.

We demonstrate numerical simulations and the experimental
realization of Nonlinear Polarization Evolution
method implemented only by using Polarization Maintaining
(PM) Fibers and a polarizing element. The all-PM-Fiber
oscillator generating 150 fs pulses has been developed.

A First-ever complete framework for robust
non-collinear propagation including
novel concepts: reference wavevector, rotated
UPPE and arbitrary Fourier rotation
will be presented accompanied by examples
of exotically phase-matched OPCPA, Fuorescence

A versatile multi-harmonic generator for efficient frequency conversion of femtosecond
pulses followed by a three-color interferometer
permits precise three-color waveform
synthesis. Its application potential is demonstrated
in experiments on the ionization of
argon.
CF-P.5 WED
Nonlinear refractive index measurement by temporal
phase reconstruction

Nonlinear refractive index has been measured in fused
silica, calcite and YVO4 at 1030 nm, by fitting the phase
contribution due to the propagation inside the material
to the temporal intensity, both reconstructed with
FROG.
