Compression of CEP-stable multi-mJ laser pulses down to 4 fs in long hollow fibers
Frederik Bohle, Martin Kretschmar, Aurelie Jullien +8
Carrier envelope phase stable 4 fs near-IR pulses with 3 mJ energy were generated by spectral broadening of circularly polarized 8 mJ pulses in a differentially pumped 2 m long com…
Inline self-diffraction dispersion-scan of over octave-spanning pulses in the single-cycle regime
M. Canhota, F. Silva, R. Weigand +1
We present an implementation of dispersion-scan based on self-diffraction (SD d-scan) and apply it to the measurement of over octave-spanning sub-4-fs pulses. The results are compa…
Orbital motions of astronomical bodies and their Centre of Mass from different reference frames: a conceptual step between the Geocentric and Heliocentric models
André G C Guerra, Paulo Simeão Carvalho
The motion of astronomical bodies and the centre of mass of the system is not always well perceived by students. One of the struggles is the conceptual change of reference frame, w…
Coherent spin-light-induced mechanisms in the semi-relativistic limit of the self-consistent Dirac-Maxwell equations
