Abstract

Single-shot acquisition of the cross-correlation between two counterpropagating short pulses is demonstrated over 150 ps using sum-frequency generation in an SBN61 crystal with random ferroelectric domains, revealing the jitter between two laser systems.

Single-shot cross-correlation of counter-propagating, short optical pulses using random quasi-phase-matching

Christophe Dorrer, Jessica Shaw

We demonstrate a single-shot cross-correlator based on the transverse sum-frequency generation of counter-propagating pulses in a disordered ferroelectric crystal. It measures the cross-correlation between the two laser pulses, leading to the relative delay between two facilities on every shot for co-timing and study of their relative jitter.

Co- and counter-propagating slow light systems

Toshihiko Baba, Keisuke Kondo

We report what we call co- and counter propagating slow-light systems based on the high nonlinearity in Si lattice-shifted photonic crystal waveguides (LSPCWs). The intense slow-light pulse, as a control pulse, efficiently generates two-photon absorption and carrier plasma effects, which tunes the dispersion characteristics of the LSPCWs and spectrum of copropagating or counter-propagating slow-light pulse, as a signal pulse. Using the control pulse, we succeeded in experimentally demonstrating adiabatic wavelength conversion and its enhancement, delay tuning of up to 10 ps with a response time <10 ps, and temporal pulse compression of factor 9.9 in the signal pulse. Furthermore, we discussed theoretically the collision and reflection of the signal pulse counterpropagating against the control pulse through the photonic-bandgap shift, resulting in a large Doppler shift. Considering the detail of these phenomena, we clarified the relation and difference between the adiabatic wavelength conversion, cross-phase modulation, and Doppler shift, which have been unclear so far.

Nonresonant EUV-UV two-color two-photon ionization of He studied by single-shot photoelectron spectroscopy

Mizuho Fushitani, Y. Hikosaka, Akitaka Matsuda +8 more

Single-shot photoelectron spectroscopy of nonresonant two-color two-photon ionization of He has been carried out using an intense free-electron laser (FEL) at 59.7 nm and a femtosecond UV laser at 268 nm. By shot-by-shot analysis of photoelectron spectra, the cross section for nonresonant two-color ionization of He is determined to be ${\ensuremath{\sigma}}^{(2)}=4.1(6)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}52}$ cm${}^{4}$ s. The cross-correlation trace derived from the nonresonant signals shows that the temporal resolution of the system is 0.36(3) ps, which is mainly governed by the timing jitter between the FEL and UV laser pulses.
