A technique is described in which electromagnetically induced transparency (EIT) spectra are used to measure laser line width. Two independent sets of EIT measurements are carried out in the presence of $^{85}Rb$ and $^{87}Rb$ atomic isotopes. Conventional self-heterodyning detection is used to obtain standard values of laser line width. A comparison shows that the estimated laser line widths in these measurements are very close to each other.
