The field autocorrelation function of single-mode 1.3 μm InGaAsP lasers has been measured using a Michelson interferometer. Comparison with theory for semiconductor laser line broadening yields the relaxation oscillation frequency, its damping rate and the linewidth broadening factor. A comparison with other techniques for lineshape measurement is presented.
