Measurements of spontaneous emission from InGaAsP semiconductor optical amplifiers provide information on both the carrier density and temperature.

Neutron measurements show that superconducting ErNi2B2C (T-c = 11 K) develops anti ferromagnetic spin density wave magnetic order (T-N = 6 K), which squares up with decreasing temperature yielding

We demonstrate a direct observation of the coherent noise spectral hole in a saturated quantum dash amplifier.

Femtosecond optical measurement techniques have been used to study the primary photoprocesses in the light-driven transmembrane proton pump, bacteriorhodopsin.

We present the first direct observation of the structure of a driven global Alfven eigenmode in a Tokamak plasma using CO(2) laser interferometry.

Neutron Compton scattering measurements presented here of the momentum distribution of hydrogen in KH2PO4 just above and well below the ferroelectric transition temperature are sufficiently sensi-t

Neutron Compton Scattering measurements of the momentum distribution of hydrogen in KDP just above and well below the ferro-electric transition temperature show clearly that the proton is tunnellin

Electromigration failure continues to be an outstanding reliability issue as future technology requires higher interconnect packing density.

We report photoluminescence measurements across the energy gap of modulation doped GaAs-(AlGa)As quantum well heterostructures.

Picosecond two-electron (shakeup) photoionization due to the soft-x-ray flux from a laser-produced plasma has been used to produce 1.3 cm sup (-1) gain in He sup + on the H-like 3 - 2 transition at
