The ability to directly measure and evaluate ultrafast processes with unprecedented time resolution and reliability has greatly extended our knowledge about the kinetics of primary processes in chemistry and allied physical and biological sciences. Improvements in the reliability and versatility of picosecond techniques should lead to an increase in ...

Picosecond spectrochronography
IEEE Journal of Quantum Electronics, 1983The general problem of extracting complete (amplitude and phase) information out of an optical signal is discussed. The authors have shown that the best one can do to determine all essential features of light pulses is to apply simultaneous temporal and spectral analysis to take spectrochronograms with the appropriate shape of the resolution cell on ...

Picosecond Switchable Azo Dyes
Chemistry – A European Journal, 2019AbstractAzo dyes that combine electron‐withdrawing thiazole/benzothiazole heterocycles and electron‐donating amino groups within the very same covalent skeleton exhibit relaxation times for their thermal isomerization kinetics within milli‐ and microsecond timescales at room temperature.

The extremely active interest in recent years in the study with picosecond pulses of nonlinear optical effects can be accounted for by a number of reasons. First, the peak power available from modelocked laser and laser amplifier systems greatly exceeds that obtainable from Q-switched and other longer pulsed lasers.

Picosecond time-resolved photoluminescence using picosecond excitation correlation spectroscopy
Journal of Applied Physics, 1988We present a study of the temporal decay of photoluminescence (PL) as detected by picosecond excitation correlation spectroscopy (PECS). We analyze the correlation signal that is obtained from two simple models; one where radiative recombination dominates, the other where trapping processes dominate.
