Effect of chirp on supercontinuum generation from Barium Zinc Borate glasses

Two Prism Critical Angle Refractometry with Attenuating Media

“…For any given sample and prism pair, that is for fixed n, k and Λ, normalised relative uncertainties U real and U im can be calculated via Equation (15). Figure 3 depicts such calculations for indicative values n = 0.75, Λ = 1.2 and variable k. In agreement with the interpretation of Figure 2, we observe that the proposed method is generally more accurate for s, than it is for p polarisation.…”

“…Typical prism-coupling refractometers [14][15][16][17] are equipped with high resolution rotary tables (see Figure 1a). Hence, the angular features of the reflectance profile (e.g., θ c ) can be resolved with high accuracy [18].…”

Radiation forces and confinement of neutral particles into the pulse envelope. New regime of collision ionization

“…The difference between the atomic and optical scales, as well as the diffraction-free and nonlinear wave-guiding regimes gives the possibility to simplify the vector Equation ( 16) to a scalar Equation (17), representing the longitudinal radiation force of a laser pulse, associated with the Poynting vector.…”

Amplification and interaction of two optical waves with third harmonic spectral delay

“…If during the interaction between the waves, it is taken into account the carrier to envelope frequency, the wavenumber mismatch ∆k becomes minimal and instead of THG new spectral components with THz spectral shift (22-26 nm) to the shorter wavelengths are generated [23,24]. For such small spectral shifts between the waves, it is possible to observe a compensation of the group velocity delay by nonlinear mechanisms [25].…”
