A longstanding goal in chemical physics has been the control of atoms and molecules using coherent light fields. This paper provides a brief overview of the field and discusses experiments that use a programmable pulse shaper to control the quantum state of electronic wavepackets in Rydberg atoms and electronic and nuclear dynamics in molecular liquids. The shape of Rydberg wavepackets was cont...

A single-beam implementation of coherent anti-Stokes Raman scattering (CARS) allows experimentally very much simplified and flexible approaches to time-resolved vibrational spectroscopy, with the additional benefit of microscopic spatial resolution. To achieve this, a broadband femtosecond laser is combined with a pulse shaper creating tailored pulse sequences by computer control. We discuss th...

We deene general concepts that extend, and simplify, the network calculus developed by Cruz 1, 2, 3] for guaranteed quality of service networks. We introduce a deenition of service curve, the extended service curve, which is the same for isolated queues and for networks of queues, and makes it possible to model nodes that otherwise do not t in the calculus of Cruz. We introduce two key technica...

The predicted spectral phase of a fiber continuum pulsed source rigorously quantified by the scalar generalized nonlinear Schrödinger equation is found to be in excellent agreement with that measured by multiphoton intra-pulse interference phase scan (MIIPS) with background subtraction. This cross-validation confirms the absolute pulse measurement by MIIPS and the transform-limited compression ...

We investigate the constant amplitude nature of several time-optimal input shaping designs for controlling exible structures. We rst discuss the equivalence of the time-optimal zero-vibration shaper with the traditional time-optimal control problem. Then we show that several robust time-optimal shaper designs for exible systems are equivalent to the time-optimal controls for diierent systems. T...

A coherent confocal microscope is proposed as a means to fully characterize the elastic scattering properties of a nanoparticle as a function of wavelength. Using a high numerical aperture lens, two-dimensional scanning, and a simple vector-beam shaper, the rank-2 polarizability tensor is estimated from a single confocal image. A method for computationally efficient data processing is described...

This paper primarily discusses two components of the MicroBooNE neutrino experiment’s preliminary tests in its final months before it commences testing. The first of these tests was a series of performance checks on the nine TPC crates designed for the experiment. Backplane beam tests, backplane supernova tests, and ASIC tests were performed extensively to ensure the TPC crates met standards fo...

The technique of input shaping has been successfully applied to the problem of maneuvering flexible structures without excessive residual vibration. With input shaping, non-negative impulse shapers are often desired because they can be used with any arbitrary (unshaped) commands and not cause actuator saturation (if these original unshaped commands do not cause actuator saturation). We outline ...
