Pulsed-power applications supporting research in fusion, plasma, and particle physics require delivery of high voltages over very short times (nanoseconds, or less)---no mean feat of engineering. The authors study current interruption in a step-recov

Quasi-phase-matched waveguides are known to degrade when generating high intensity short wavelength light. Photoinduced changes in the refractive indices can lead to reduced efficiency by broadening phase-matching curves or inducing power dependent l

In this letter, we demonstrate an optically pumped semiconductor disk laser frequency doubled with a periodically poled lithium tantalate crystal. Crystals with various lengths were tested for intracavity frequency conversion. The semiconductor disk

In this work a method is presented that permits the evaluation of the bulk and surface electronic properties of p‐type Hg0.77Cd0.23Te epilayers grown by metalorganic chemical‐vapor‐deposition and liquid‐phase‐epitaxy growth techniques. The

We have investigated the properties of CdTe/Hg0.77Cd0.23Te heterostructures in order to evaluate the use of thin CdTe cap layers for passivation of the HgCdTe surfaces. The energy band diagram across the interface of this structure was calculated usi

There has been an increasing interest in compact coherent sources at 600 nm for a number of applications, e.g. orange-red components for laser projection displays [1], and excitation sources in photodynamic therapy [2]. The need for these sources bec

Planar n/sup +/p Hg/sub 1-x/ Cd/sub x/Te (x=0.23) photodiodes passivated with ZnS were irradiated by a Co/sup 60/ gamma source. A strong increase in the reverse dark current was observed for doses above 0.3 Mrad(air). A similar effect is found by exp

We propose and demonstrate a nonlinear parametric amplification system that relies on sequential use of a nonlinear phase shift (Kerr-like effect) and on phase-sensitive parametric amplification. We demonstrate amplification that is 50% better than w
