Abstract

An automatic in-flight method for tuning lasers to selected absorption lines of gases in the atmosphere has been investigated. The method has been developed as part of a system for the determination of water vapor in the atmosphere from an airborne platform. It is demonstrated by numeric simulation that a tuneable alexandrite laser can be adjusted to within 0.5 picometers of a desired wavelength within a data gathering and computational period of less than ten minutes. Numeric simulations were used to investigate potential sources of error. The method was analyzed for a NASA water vapor differential absorption instrument now being constructed, however, the method may be useful for other atmospheric gases.
