Time-resolved phonon-assisted stimulated emission in quantum-well heterostructures
1989 Edition, Volume 36, November 1, 1989 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Summary form only given. The authors report the observation of time-resolved photo-pumped operation of phonon-assisted stimulated emission in a series of AlGaAs-GaAs single quantum wells with different well thicknesses (20, 34, and 54 AA). The temporal characteristics of...

Characteristics of stimulated emission from CdS by electron-beam pumping
1970 Edition, Volume 6, February 1, 1970 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The results of electron-beam experiments on undoped single-crystal CdS are presented. A description of the beam-injection apparatus is given. The relevance of various indications for lasing in this type of structure is discussed, and an operational definition of...

Polarized stimulated emission of ZnO microbox
2009 Edition, August 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The polarized emission from nano-structured micro boxes of ZnO has been measured with ultrafast time-resolved laser spectroscopy and the relationship between photoluminescent (PL) mechanisms and corresponding degrees of polarization has been discussed.

Stimulated emission from ZnO nanorods synthesized by pulsed-laser deposition
2003 Edition, Volume 2, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We succeeded in synthesizing ZnO nanorods by pulsed-laser deposition (PLD) at comparatively high gas pressure without using any catalyst. Stimulated emission was observed from ZnO nanorods at 388 nm by optical pumping. It is found that nanoparticles formed...

Locating Noncooperative Radio Receivers Using Wideband Stimulated Emissions
2013 Edition, Volume 62, March 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Accurately determining the position of radio receivers can aid in the rapid discovery of radio-controlled explosives. Prior research has demonstrated that superheterodyne receivers unintentionally emit low-power radio signals during normal operation. By using a weak stimulation...

A further discussion of stimulated emission of bremsstrahlung
1963 Edition, Volume 42, March 1, 1963 - AT&T Corp.

In an earlier paper1 we proved the existence of stimulated emission of bremsstrahlung for electrons moving in the vicinity of nuclei. However, no estimate of the available power was given at that time. This paper extends the theory to the fourth order of...

Temperature dependence of the stimulated emission in a conjugated polymer
1999 Edition, January 1, 1999 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Summary form only given. With their combined light-emission and electronic transport functionality, PPV and its derivatives are currently investigated for various applications including light-emitting diodes and lasers. Although, the report of stimulated...

Stimulated Emission by Ballistic Electrons in Semiconducting Superlattices
1989 Edition, January 1, 1989 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The spontaneous emission by ballistic electrons which traverse a superlattice yields as many as 5.10/sup 8//sec IR photons for an injected current of 100/spl mu/A into a 5x20/spl mu/m/sup 2/ device. Based on this result we obtain the rate of stimulated emission...

Automated hemochromatosis spectra analysis using neutron stimulated emission tomography
2012 Edition, October 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We identified and diagnosed hemochromatotic cases with an automatic technique based on peak recognition and chemometrics. Hemochromatosis is a disease characterized by an accumulation of iron in body organs. Neutron-stimulated emission computed tomography (NSECT)...

Neutron stimulated emission computed tomography for brain cancer imaging
2013 Edition, October 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Neutron stimulated emission computed tomography (NSECT) uses photons emitted from inelastic scattering of neutrons with biological objects to quantify the elemental composition of the object and reconstruct an image. Previously, NSECT has been used to detect liver and...
