Aberrations in temporal imaging

Bounce-by-Bounce Cavity Ring-Down Spectroscopy: Femtosecond Temporal Imaging

“…This topology was confirmed later by direct ab initio calculations. [8,12] Ab initio results [7,12,13] for Ar ± X 2 (X Cl, Br, I) consistently approached, with increasing accuracy but still underestimated the experimental D 0 values, and predicted an increase in binding compared to the DIM results based on equivalently accurate ab initio Ar ± X potentials. This means that the (effective) Ar ± I interactions become more attractive within the Ar ± I 2 complex and, hence, D 0 (T) b 206 cm À1 could be expected in terms of the empirical Ar ± I data, consistent with the older, but not with the new, experimental results.…”

“…This is larger than the new experimental value but smaller than the older one by about 30 cm À1 , the latter difference being the same as for similar Ar ± Cl 2 results. [7] It therefore appears that there might be a mismatch between the Ar ± I and new Ar ± I 2 experimental data interpretations.…”

“…When such perturbations of the Ar ± Cl interactions obtained from accurate ab initio calculations were transferred to the DIM results based on reliable empirical diatomic input, the measured D 0 value for Ar ± Cl 2 was reproduced within its experimental uncertainties with no fitting. [7] Ab initio data for Ar ± I and Ar ± I 2 sufficiently accurate for similar reliable predictions are yet to be obtained.…”

Quantum temporal imaging: application of a time lens to quantum optics

“…In this limit and in the practically important case of • for a non-collinear type-I phase-matching of pump and signal waves at 830 nm and the idler wave at 415 nm, as in Ref. [14]. Dotted lines show the signal and the idler bands.…”

“…The key element of a temporal imaging system is time lens, introducing a quadratic in time phase modulation into the signal field. Optical time lenses presently are based on electro-optical phase modulation [4,5,6,7,8], sum-frequency generation (SFG) [9,10,11,12,13,14,15], or four-wave mixing [16,17,18,19] and provide a temporal magnification up to 100 times.…”
