We present evidence of MMF noise and introduce an algorithm that predicts the amplitude of the noise as a function of parameters such as core diameter, fiber length, and spectral resolution. Presented Thursday 16 August 2007 at the Gordon Research Conference on Laser Diagnostics for Combustion, Oxford, United Kingdom. 2008-06-09T00:00:00Z http://digital.library.wisc.edu/1793/28167 Frequency Combs and Hyperspectral Sources for Absorption Spectroscopy Sanders, Scott T. We continue to develop laser sources for high-speed gas absorption spectroscopy. A recent source cycles through 14 wavelengths in the 1325-1666nm range every 33 microseconds for combined measurements of gas temperature, H2O, and CH4. Presented 5 May 2008 at the Conference on Lasers and Electro-Optics (CLEO) conference, San Jose, CA. 2008-05-05T00:00:00Z http://digital.library.wisc.edu/1793/24391 Designs and Applications of Hyperspectral Light Sources Sanders, Scott T. A time-division multiplexed source that cycles through 19 wavelengths every 15 s will be described. Sensing results using this and similar sources will follow, including gas thermometry at 100kHz with a precision of 4K at 2000K. Presented 19 March 2008 at the Laser Applications to Chemical, Security, and Environmental Analysis (LACSEA) conference, St. Petersburg, FL. 2008-04-01T14:06:49Z
