We describe a wavelength conversion experiment (generation of a pulse at the wavelength λp - Δλ from a signal at λp+Δλ under the action of a pump at λp) performed through cascaded second-order process in a lithium niobate channel waveguide. Wi

We report an accurate set of Sellmeier coefficients for the N-(4-nitrophenyl)-L-prolinol (NPP) crystal, obtained by improving a previously proposed set through the measurement of the phase-matching angle for second harmonic generation. Our Sellmeier

We report the two-photon absorption (TPA) spectrum of a film of poly[4,6-dacadiyne-1,10-diolbis(3-butoxycarbonyl-methyl-urethane)]—commonly known as poly(3-BCMU)—in the wavelength range λ=1.6–0.7 μm. We find that the TPA coefficient of the fi
