Femtosecond coincidence imaging of multichannel multiphoton dynamics.
The novel technique of femtosecond time-resolved photoelectron-photoion coincidence imaging is applied to unravel dissociative ionization processes in a polyatomic molecule. Femtosecond coincidence imaging of CF3I photodynamics illustrates how competing multiphoton dissociation pathways can be distinguished, which would be impossible using photoelectron or ion imaging alone. Ion-electron energy...
متن کاملNote: Scalable multiphoton coincidence-counting electronics.
We present a multichannel coincidence-counting module for use in quantum optics experiments. The circuit takes up to four transistor-transistor logic pulse inputs and counts either twofold, threefold, or fourfold coincidences, within a user-selected coincidence-time window as short as 12 ns. The module can accurately count eight sets of multichannel coincidences, for input rates of up to 84 MHz...
متن کاملMultiphoton Fluorescence Correlation Spectroscopy (MPFCS)
Nanoparticles have been demonstrated as a promising new generation of specific imaging agents and targeted delivery vehicles for the diagnosis and treatment of solid tumors. Nonetheless, for optimal therapy of tumors, the nanoparticles must penetrate the tumor interstitial matrix to reach the cancer cells. This thesis describes the development of a multiphoton fluorescence correlation spectrosc...
متن کاملAn FPGA-based module for multiphoton coincidence counting
We present a multi-channel coincidence-counting module for use in quantum optics experiments. The circuit takes up to four TTL pulse inputs and counts either 2-, 3-, or 4-fold coincidences, within a user-selected coincidence time window as short as 12 ns. The module can accurately count eight sets of multi-channel coincidences, for input rates of up to 84 MHz. Due to their low cost and small si...
متن کاملPerturbative Corrections to Photon Coincidence Spectroscopy Perturbative Corrections to Photon Coincidence Spectroscopy 2
Whereas photon coincidence spectroscopy is a promising technique for probing the nonlinear regime of cavity quantum electrodynamics in the optical domain, the accuracy is mitigated by two factors: higher–order photon correlations, which contribute to an enhanced pair count rate, and non– simultaneity of emitted photon pairs from the optical cavity. We show that the technique of photon coinciden...
