Stimulated emission from co-doped zinc-aluminosilicate glass ceramics
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Glass ceramic materials containing tetrahedral divalent cobalt ions have been recently introduced as laser saturable absorbers. Here we present study of stimulated emission from co-doped zinc-aluminosilicate glass ceramics (Co:ZAS).

A Practical Superheterodyne-Receiver Detector Using Stimulated Emissions
2011 Edition, Volume 60, April 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The accurate and timely discovery of radio receivers can assist in the detection of radio-controlled explosives. Superheterodyne receivers emit low-power radio signals during normal operation. These are known as unintended emissions. In this paper, the unintended...

Stimulated emission dynamics in self-assembled InAs/GaAs quantum dots
2000 Edition, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Summary form only given. Self-assembled semiconductor quantum dots have found interest as gain materials for semiconductor lasers. While time-resolved studies on quantum dots have mainly focused on the spontaneous recombination dynamics, little is known about the dynamics of...

Anomalous magneto-plasmonic spectra: evidence for stimulated emission or superradiance?
2005 Edition, Volume 2, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Novel magneto-plasmonic emission phenomena are observed from excited Landau levels in In/sub x/Ga/sub 1-x/As quantum wells when pumped using intense femtosecond laser excitation in strong magnetic fields (25 T). The emission...

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...

Long-wavelength stimulated emission in HgCdTe quantum well waveguide heterostructures
2016 Edition, September 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We report on stimulated emission (SE) at wavelengths up to 10.2 μm from waveguide HgCdTe structures with several quantum wells (QWs) inside the waveguide core. The onset of the SE takes place under optical pumping with intensity as low as 0.12 kW/cm2...
