Highly oriented polycrystalline thin films of lithium niobate on (012), (100), and (110) sapphire single crystal substrates, (111) silicon and SiO$\sb2$/(100)Si wafers were grown by magnetron rf sputtering and metallo-organic ...

Design, development, and application of novel all-solid-state spectroscopic gas sensors is reported. These compact instruments employ mid-infrared difference-frequency generation pumped by room-temperature semiconductor ...

Electron spin-polarized helium 2$\sp3$S$\sb1$ metastable atoms are a valuable probe of spin-dependent phenomena. Helium metastable atoms can be polarized by illumination with circularly-polarized 1.083 $\mu$m 2$\sp3$S$\sb1 ...

The generation of substantial electrical conductivity in high temperature polymers and thin film C$\sb{60}$ by means of KrF (248 nm) excimer laser irradiation has been investigated. Formation of both laser ablated surface ...

Very short wavelength lasers have many potential scientific and technological applications. A practical extreme ultraviolet (XUV) laser system has been developed using the Xe Auger laser at 109 nm. This system is the first ...

Fiber optic networks capable of supporting a large pool of subscribers, many simultaneous users, and high data rates are receiving heightened interest as solutions to a growing communications need. The experiments reported ...

The theory of difference frequency generation has been further developed. Derived from basic principles, the equations developed here accurately predict the conversion of power to the idler wave. Critical phasematching can ...
