This time-domain bound-state interferometry reveals several new aspects of the dynamic evolution of wave packets in the presence of strong laser fields.Abstract:
We have studied the evolution of regular and ``dark'' radial wave packets under the influence of two coherent, temporally separated 100 fs laser pulses. The atomic states are probed by ramped-field ionization. The final state populations exhibit Ramsey oscillations with periods ranging from 2.6--1000 fs as a function of the delay between the two pulses. This time-domain bound-state interferometry reveals several new aspects of the dynamic evolution of wave packets in the presence of strong laser fields. Lowest order perturbation theory is inadequate to describe wave packet formations, even at the lowest intensities studied.read more

A "Schrodinger Cat" Superposition State of an Atom
TL;DR: A “Schrödinger cat''-like state of matter was generated at the single atom level by application of a sequence of laser pulses, which entangles internal and external states of the ion.

Control of quantum phenomena: past, present and future
TL;DR: Adaptive feedback control (AFC) as mentioned in this paper is a state-of-the-art technique for quantum control. But it is not suitable for the case of femtosecond laser sources.

TL;DR: This review presents a summary of some of the most salient contributions to the field of coherent laser control from an experimentalist's perspective and highlights the fact thatSome of the highest resolution spectroscopic measurements being carried out employ femtosecond laser pulses.

Control system and apparatus for use with ultra-fast laser
TL;DR: In this paper, a control system and apparatus for use with an ultra-fast laser is described, which includes a laser, pulse shaper, detection device and control system, and a multiphoton intrapulse interference method is used to characterize the spectral phase of laser pulses.
