Physical properties of short wavelength 2.6µm InAs/AlSb-based quantum cascade lasers
2010 Edition, September 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We used high hydrostatic pressure techniques to understand the deteriorating temperature performance with decreasing wavelength of short wavelength quantum cascade lasers. Influence of inter-valley scattering and distribution of the...

Short wavelength FELs
1991 Edition, January 1, 1991 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The generation of coherent ultraviolet and shorter wavelength light is presently limited to synchrotron sources. Even though synchrotrons can produce a wide range of wavelengths, the output power in a narrow bandwidth is limited relative to that attainable by...

Short-wavelength lasers
1992 Edition, Volume 80, March 1, 1992 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The development of short-wavelength lasers is reviewed. Three pumping mechanisms have been demonstrated which produce lasing at wavelengths from 3 to 100 nm. These mechanisms include electron-collisional excitation, electron-ion recombination, and photo-excitation...

Short-Wavelength Free-Electron Lasers
2010 Edition, Volume 2, April 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper presents a short review of the development of and the motivation for short-wavelength free-electron lasers. The first observation of coherent X-ray production was reported from the Linac Coherent Light Source in April 2009.

Short-wavelength target modeling
1984 Edition, Volume 32, January 1, 1984 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A simplified model has been employed to review the scattering characteristics of targets in the short wavelength limit. It is demonstrated that the reflected signal can be modeled as a diffuse plus a finite number of coherent returns (also called glints). It is then...

Short-wavelength Yb:Fiber laser
2012 Edition, July 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The small ratio between emission and absorption cross sections below 980 nm hinders Yb:fiber laser's development. The temperature, fiber length, and suppression of high-gain wavelengths are analyzed and a 960-nm laser is successfully developed.

Recent progress in short wavelength quantum cascade lasers
2011 Edition, July 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The 3-4μm wavelength range is of key technological importance for a wide range of applications. As a consequence of the strong fundamental C-H stretch mode that occurs at around 3.3μm, the detection of many important hydrocarbon species has maximum sensitivity...

Performance Analysis of Short-Wavelength Infrared Optical Sensors
2019 Edition, July 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We report in this paper our latest results on fabrication and testing of optical sensor for imaging in short-wavelength infrared regime. We are comparing the performance of our imaging sensor in two permitted regimes by the readout integrated circuit used.

Physical Properties of Metalorganic Thin Films
2018 Edition, July 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This work contains description of the physical properties of the organometallic thin films. We present investigation results of the structural and optical properties of the thin films containing manganium bis-(8-hydroxyquinoline) and iron and...

Study of Short-Wavelength Yb:Fiber Laser
2012 Edition, Volume 4, December 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Yb:fiber lasers have shown excellent performance in 980- to 1100-nm wavelength range. Below 980 nm, the small ratio between emission and absorption cross sections hindered its development. To find out a feasible solution for short-wavelength Yb:fiber laser, the...
