Because of their apparent “simplicity” simple atoms present a great challenge
and temptation to experts in various branches of physics from fundamental problems
of particle physics to astrophysics, applied physics and metrology. This
book is based on the presentations at the International Conference on Precision
Physics of Simple Atomic Systems (PSAS 2002) whose primary target was to
provide an effective exchange between physicists from different fields.
When I was first approached to edit a volume on Femtosecond Laser
Spectroscopy in 2000, I did not anticipate that the field was about to explode,
with the announcement of a series of remarkable new developments and
advances. This volume describes these recent developments in eleven
chapters written by leading international researchers in the field. It includes
Femtosecond optical frequency combs, which are currently
revolutionising ultrahigh precision spectroscopy and optical frequency
Precision measurement of structures in the micrometer and sub-micrometer
ranges is becoming more and more important. Because of the never-ending miniaturization
it is central to the precision of production and metrology of microelectronics
and micromechanics, but also to the measurement of the size distribution
of microparticles, for example, in environmental protection. A number of measuring
methods are available to perform these tasks.
The Gauge Block Handbook by Ted Doiron and John Beers Dimensional Metrology Group Precision Engineering Division National Institute of Standards and Technology Preface The Dimensional Metrology Group, and its predecessors at the National Institute of Standards and Technology (formerly the National Bureau of Standards) have been involved in documenting the science of gauge block calibration almost continuously since the seminal work of Peters and Boyd in 1926 .
Over the last few years, there has been a convergence between the fields
of ultrafast science, nonlinear optics, optical frequency metrology, and
precision laser spectroscopy. These fields have been developing largely
independently since the birth of the laser, reaching remarkable levels of
