A hyperspectral imaging system was used to monitor vegetation during a subsurface controlled release of carbon dioxide (CO2). From August 3 to 10, 2007, 0.3 tons CO2/day were released through a 70 m horizontal pipe located at a nominal depth of 1.8 m

In this paper, we describe how to phase and frequency stabilize a continuous wave (CW) Raman laser. We model and measure the transfer function of a high-finesse cavity filled with a Raman active gas. In addition, we model the time dependence of the t
