The dye laser analysis depends on the gain equation that contains cross sections of the relevant emission and absorption molecular transitions involved in the lasing process. The absorption cross-section σs (v) is directly related to the absorbance curves of the dye. The emission cross-sectionσem (v) has been derived in terms of directly measurable spectroscopic quantities. The low frequency tail of the absorption curves is minutely diminishing for very dilute solutions(~=10-5 mole/lit) usually used in laser system. This low frequency tail overlaps the operating frequency band of the laser. The linear dependence of the dye absorption on the dyeconcentration (Beer- Lambert law), is used to solve the low frequency tail problem. The intrinsic gain characteristics are calculated for the dye Rhodamine "B" and the results are in good agreement with the reported experimental results.
