We report a new SBN-tellurite ceram-glass system, where the [(SrO)(y)(BaO)(1−y) (Nb2O5)](1−x) (SBN) ferroelectric crystallites precipitate on a tellurite (TeO2)x glass surface with nominal compositions x < 0.8 and y = 0.6 to 0.75. X-ray diffracti

The kinetics of photoinduced defect formation in high-purity silicas has been studied by femtosecond transient absorption spectroscopy in the visible and ultraviolet. Band edge two-photon excitation produces singlet excitons which decay in 0.25 ps in

A technique for characterizing pulsed far-infrared radiation with a demonstrated resolution of approximately 100 fs is used to measure directly Cooper pair breaking in superconducting lead. A 100-fs pulse of visible light is used to excite a thin-fil

We report on a direct kinetic measurement of Cooper-pair breaking in superconducting lead. A 100-fs pulse of visible light was used to excite a thin-film lead sample, while the Cooper-pair density was optically probed using an ultrashort pulse of bro

We show that far-infrared radiation can be generated in the depletion field near semiconductor surfaces via the inverse Franz-Keldysh effect or electric-field-induced optical rectification. This mechanism is conceptually different from those previous

Femtosecond pulses of far-infrared (FIR) radiation can be generated in the depletion field near semiconductor surfaces under optical excitation via the inverse Franz-Keldysh effect or electric-field-induced optical rectification. This coherent mechan

This paper spectroscopically characterizes elementary electronic excitations in ${\mathrm{BaBiO}}_{3}$. We have utilized pump-and-probe spectroscopic techniques which have identified a single transient spectrum subsequent to either pulsed optical or

Recognition that organic solids possess some of the largest all-optical nonlinearities of all known materials has resulted in an interdisciplinary effort directed at both the basic understanding and exploitation of these effects. Parallel efforts on

Guided acoustic‐wave Brillouin scattering (GAWBS) measurements were performed on 20‐cm lengths of optical fibers with particular attention focused on the lowest lying resonance. In 125‐μm‐diam silica fibers, this resonance was observed to oc

The crystallographic orientation dependence of the far‐infrared (FIR) light generated at the (001) surface of a zincblende semiconductor is shown to derive principally from bulk difference‐frequency mixing. A strong modulation is observed for 1
