Calibration Service for Laser Power and Energy at 248 nm

January 1, 1998
Author(s)
Rodney W. Leonhardt
This document describes the calibration service provided by the National Institute of Standards and Technology (NIST) for laser power and energy at the excimer laser wavelength of 248 nm. The service supports the calibration of laser power meters form 400

Coherent Quantum State Manipulation of Trapped Atomic Ions

January 1, 1998
Author(s)
David J. Wineland, C Monroe, D M. Meekhof, B E. King, Dietrich G. Leibfried, Wayne M. Itano, James C. Bergquist, D J. Berkeland, John J. Bollinger, J D. Miller
A single, laser-cooled, trapped 9Be+ ion is used to investigate methods of coherent quantum-state synthesis. We create and characterize nonclassical states of motion including "Schrödinger- cat" states. A fundamental quantum logic gate is realized using

Combining Interactive Exploration and Optimization for Assembly Design

January 1, 1998
Author(s)
Simon Szykman, Gerard Kim
This paper presents an integrated framework for assembly design. The framework will allow the designer to represent knowledge about the design process and constraints as well as information about the artifact being designed, design history and rationale

Comments on Vibrational Dynamics of Low Frequency Adsorbate Motion

January 1, 1998
Author(s)
B N. Persson, John William Gadzuk
We discuss the temperature dependence of the electronic damping of adsorbate vibrations, as probed by pump-and-probe and infrared spectroscopy. Incontrast to recent suggestions, we show that the damping is strictly temperature independent as long as the
