Theoretical analysis of effect of Langmuir flow in ring laser
Abstract
The flow of gas in a gain medium is an important source of error in laser gyros. The drift of the frequency difference of opposite carrier waves brought about by the flow of active and nonactive atoms in the gain medium is discussed. The theoretical formula and the computed values of Langmuir flow in the third order theory are given. The use of statistical methods to treat the drift of frequency difference when a Gaussian beam passes through the gain field and the flow velocity field is emphasized. The computational formulas for various conditions are presented.
