Amanda Gogates, product manager for Rosemount Quantum Cascade Laser
Analyzers, Emerson Automation Solutions, said: "In ethylene manufacturing and natural gas processing for example, establishing the purity of the gas is essential to meeting contractual requirements as well as maintaining process optimisation and safety.
Terahertz free space communications demonstration with quantum cascade laser
and quantum well photodetector // Electronics Letters.
Having a quantum cascade laser
as a source increases the range so significantly that it becomes a viable device for search and rescue," says Patel.
Unlike conventional interband semiconductor lasers, such as those used in DVD players, the quantum cascade laser
(QCL) is an intersubband device that requires only electrons to operate.
Like all analyzers in the CT5000 family, the CT5800 combines tunable diode laser (TDL) and quantum cascade laser
technologies within the same analyzer.
9 March 2017 - Italian infrared research and product development company Leonardo, through the US subsidiary Leonardo DRS, has signed a definitive agreement to purchase US-based quantum cascade laser
products and technology developer Daylight Solutions, Inc.
Through the integration of Quantum Cascade Laser
(QCL) technology, Spero breaks the existing paradigm in infrared microscopy to open new applications and markets.
The phenomenon was discovered, by a Princeton University led team, in a type of device called quantum cascade laser
, in which an electric current flowing through a specially designed material produces a laser beam.
Topics include light emission in aperiodic Thue-Morse dielectrics, development of a SiGe quantum cascade laser
, electric force microscopy of individually charged silicon nanoparticles, surface cusp formation in silicon homoepitaxy, and optical activation of nanowires using Er-doped sol-gel derived silica.
A paper explaining the work, "Optically induced fast wavelength modulation in a quantum cascade laser
," was recently published in Applied Physics Letters.
The enhanced Quantum Cascade laser
system, the Developer version, includes a Developer QC Laser module, a control module and an interface card.
A photoacoustic cell is surprisingly simple and inexpensive to produce, with all of the cost and size driven primarily by the packaging of the quantum cascade laser
array," he adds.
