| Abstract: | The formula of COIL sign gain is derived approximately under the saturation conditions, in case that particles occupying the hyperfine sublevels of each electric level are at thermal equilibrium. The rule that the COIL central transition frequencies change with the iodine density is also achieved by using this formula. Related analysis results and discussion are given. |
