Modal analysis using photonic lanterns coupled to arrays of waveguides
Momen Diab, Stefano Minardi
We present a new concept of an integrated optics component capable of measuring the complex amplitudes of the modes at the tip of a multimode waveguide. The device uses a photonic…
Energy deposition dynamics of femtosecond pulses in water
Stefano Minardi, Carles Milián, Donatas Majus +5
We exploit inverse Raman scattering and solvated electron absorption to perform a quantitative characterization of the energy loss and ionization dynamics in water with tightly foc…
Higher-order Kerr effect and harmonic cascading in gases
Morten Bache, Falk Eilenberger, Stefano Minardi
The higher-order Kerr effect (HOKE) has been recently advocated to explain measurements of the saturation of the nonlinear refractive index in gases. Here we show that cascaded thi…
Astrointerferometry with discrete optics
Stefano Minardi, Thomas Pertsch
We propose an innovative scheme exploiting discrete diffraction in a two dimensional array of coupled waveguides to determine the phase and amplitude of the mutual correlation func…
Time-resolved refractive index and absorption mapping of light-plasma filaments in water
Stefano Minardi, Amrutha Gopal, Michael Tatarakis +4
By means of a quantitative shadowgraphic method, we performed a space-time characterization of the refractive index variation and transient absorption induced by a light-plasma fil…
Quantitative two-dimensional shadowgraphic set-up for high-sensitivity measurement of low-density laser-plasmas
Amrutha Gopal, Stefano Minardi, Michael Tatarakis
We present a quantitative shadowgraphic method which can measure the density of a laser-generated plasma in air with sensitivity and resolution comparable or better than traditiona…
