The linewidth enhancement factor alpha is measured in a number of GaAlAs lasers with different internal losses. It is found that alpha decreases monotonically with the increase of the loss (Fermi energy level) in agreement with the theoretical prediction. On the basis of these results the design of cavity length and mirror reflection in order to reduce the spectral linewidth of the laser output is discussed.
