Design and Fabrication of Micro-electro-mechanical Systems Actuators for Application in External Cavity Tunable Lasers
DownloadFall 2014
The limited availability of rugged and economical infra-red laser sources that can be tuned over a certain wavelength range is still a bottleneck for widespread application of spectroscopic methods to environmental, industrial, and medical trace gas monitoring. Conventional semiconductor lasers...

Development of a Mid-infrared Detection System for Real-time Measurements of Gas Phase Benzene, Toluene, Ethylbenzene and Xylenes using a Tunable External Cavity Quantum Cascade Laser
DownloadSpring 2012
The chemical transformation of trace gases, including reactions that result in aerosol particle formation, as well as the composition of the atmosphere deeply influence air quality and Earth's global climate. Use of a simulation chamber to study smog formation is a common method to investigate...

Spectroscopy of methane using a vertical cavity surface-emitting laser system with emphasis on development for portable applications
DownloadFall 2009
There is a great deal of interest in monitoring atmospheric greenhouse gases such as methane. Although distributed feedback edge-emitting lasers are often used for atmospheric detection, the development of the vertical cavity surface-emitting laser (VCSEL) has allowed for an alternative source....
