Flat focusing mirrors
(Institute of Electrical and Electronics Engineers (IEEE), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialWe present the flat focusing mirror - the dielectric mirrors capable to focus and image the narrow beams in reflections. The mirrors are flat, and transversally invariant, i.e. have no optical axis. We consider two different ... -
Photonic crystals for suppression of filamentation
(International Society for Photo-Optical Instrumentation Engineers (SPIE), 2022)
Text en actes de congrés
Accés restringit per política de l'editorialIn this work we show the prospect of using periodic refractive index modulation – photonic crystals – to control the spatial dispersion curvature in a way that could potentially counteract the Kerr effect, thus suppressing ... -
Ultrashort pulse chirp measurement via transverse second-harmonic generation in strontium barium niobate crystal
(2015-06-01)
Article
Accés obertPulse compression in dispersive strontium barium niobate crystal with a random size and distribution of the anti-parallel orientated nonlinear domains is observed via transverse second harmonic generation. The dependence ...
