Book Description
For my thesis, I worked towards using two reference cavities to provide frequency stabilization to a 486nm dye-ring laser. After a doubling cavity doubles the frequency to 243nm, the laser beam is used to excite ground state hydrogen to the 2S state: the first step of an experiment to accurately measure the 2S-NS transitions of hydrogen and measure the Lamb shift and Rydberg's constant. Two stabilization cavities were used to prevent the frequency from drifting and to narrow the laser's line-width. I aligned the majority of the optics and coupling light into fiber-optic cables and Fabrey-Perot cavities. Coupling light into a high finesse Fabrey-Perot cavity requires matching the radius of curvature of constant phase of the laser with the geometry of the cavity. To do this, I first measured the physical properties of the laser beam and then numerical arrived at a solution using two lenses to match the conditions imposed by the cavity's geometry. I aligned the cavity and then observed a Pound-Drever-Hall error signal. This error signal will be fed back into the laser to stabilize the frequency. It is anticipated that when the electronics to utilize the error signals are completed, the laser frequency will be stabilized to a hundred hertz, an four order of magnitude improvement over the stability provided by the commercial laser.

Book Description
This volume contains the lectures and seminars presented at the NATO Ad vanced Study Institute on "Solid State Lasers: New Developments and Appli cations" the fifteenth course of the Europhysics School of Quantum Electronics, held under the supervision of the Quantum Electronics Division of the European Physical Society. The Institute was held at Elba International Physics Center, Marciana Marina, Elba Island, Tuscany, Italy, August 31 -September 11, 1992. The Europhysics School of Quantum Electronics was started in 1970 with the aim of providing instruction for young researchers and advanced students al ready engaged in the area of quantum electronics or wishing to switch to this area from a different background. Presently the school is under the direction of Professors F.T. Arecchi and M. Inguscio, University of Florence, and Prof. H. Walther, University of Munich, and has its headquarters at the National Insti tute of Optics (INO), Florence, Italy. Each time the directors choose a subject of particular interest, alternating fundamental topics with technological ones, and ask colleagues specifically competent in a given area to take the scientific responsibility for that course.

ISBN: 9814548553
Category :
Languages : en
Pages : 474
Book Description
The book includes all the recent major advances in the field of Laser Spectroscopy. Major results span from the control of matter by electromagnetic fields (trapping and coding) to high precision measurements on simple atomic systems and to quantum optics with single atoms. As an outstanding contribution, the reader will find in the book the first report of the Bose-Einstein condensation achieved by laser-cooling of rubidium atoms. Achievements in the technology of tunable sources, in particular of miniaturized solid state devices, are also reported. Most recent advances in molecular spectroscopy are illustrated with emphasis on 'cooled' spectra, clusters and high accuracy frequency references. Topics such as atomic interferometry and microcavity quantum optics are also covered.

Time and Matter

ISBN: 9812774394
Category : Science
Languages : en
Pages : 338
Book Description
Time and matter are the most fundamental concepts in physics and in any science-based description of the world around us. Quantum theory has, however, revealed many novel insights into these concepts in non-relativistic, relativistic and cosmological contexts. The implications of these novel perspectives have been realized and, in particular, probed experimentally only recently. In the papers in this proceedings, these issues are discussed in a truly interdisciplinary fashion from philosophical and historical perspectives. The leading contributors, including Nobel laureates T W Hnnsch and G t'' Hooft, address both experimental and theoretical issues. Sample Chapter(s). Chapter 1: The Measurement to Time with Atomic Clocks (742 KB). Contents: Measuring Time; Causality and Signal Propagation; Coherence and Decoherence; CP and T Violation; Macroscopic Time Reversal and the Arrow of Time; New Paradigms. Readership: Physicists, philosophers and historians of science, graduate students of physics."

Book Description
This introduction to Atomic and Molecular Physics explains how our present model of atoms and molecules has been developed during the last two centuries by many experimental discoveries and from the theoretical side by the introduction of quantum physics to the adequate description of micro-particles. It illustrates the wave model of particles by many examples and shows the limits of classical description. The interaction of electromagnetic radiation with atoms and molecules and its potential for spectroscopy is outlined in more detail and in particular lasers as modern spectroscopic tools are discussed more thoroughly. Many examples and problems with solutions should induce the reader to an intense active cooperation.
