This volume originated in a happy event honoring Arthur Schawlow on his 65th birthday. As a research physicist, Schawlow has been a major infiuence on the present nature of physics and of high technology. He has also had a role, through the American

Polarization-selective optical heterodyne detection is shown to enhance the practical sensitivity of cavity ring-down spectroscopy. Initial experiments demonstrate a signal-to-noise ratio above 31 dB. Minor improvements should yield shot-noise-limite

Physicists have always been fascinated by the very small. These days, the inner structures of everyday items such as the personal computer fall into that size category and warrant our interest. The critical dimensions of individual features of state

The polarization sensitive optical heterodyne methods used to detect polarization rotations in conventional magnetooptic data storage systems can be altered to produce nonzero electronic signals only when the polarization rotation changes. Such syste

We have combined frequency-modulation and polarization spectroscopy to detect anisotropic spectral features with high sensitivity. The many line shapes possible with this technique and the potential for laser noise suppression were demonstrated by us

We have used FM spectroscopy to detect the stimulated Raman gain effect in deuterium, demonstrating for the first reported time the quantum-noise-limited performance of this technique.

Polarization spectroscopy was used for the first time known to the authors to measure the homogeneous linewidth and excited-state lifetime of an inhomogeneously broadened transition of an absorbing impurity ion in a crystalline host. The observed lin

This is the first reported observation of a second-order Raman spectrum by means of coherent Raman spectroscopy. Optically heterodyned Raman-induced Kerr-effect spectroscopy was used to study the two-phonon Raman peaks of a highly fluorescent sample

Polarized and depolarized components of the quasielastic light-scattering spectrum of fused-silica optical fiber have been measured in the frequency range 100 kHz to 100 MHz at temperatures from 10 to 293 K. The depolarization ratio was found to be 0

Vortex masks composed of rectangles with nominal phases of 0°, 90°, 180° and 270° have been shown to print sub-100nm vias and via arrays when projected into negative resist using 248nm light. Arrays with pitches down to 210nm and CDs as small as
