This is a report on research directed toward the development of a coal-mine methanometer. The project encompassed two tasks. The first was a study conducted to determine if room-temperature injection lasers could be used as the source for a DIAL methanometer for coal-mine applications. As part of that study, prior DIAL measurements of methane were reviewed and the measurement technique explored in general. The second task was the design and fabrication of an external grating cavity to reduce the bandwidth of the injection lasers.
