Abstract
We report here the experimental observation of power-independent linewidth broadening of cw single-frequency (GaAl)As diode lasers. This phenomenon is attributed to refractive index fluctuations resulting from statistical fluctuations in the number of conduction electrons in the small active volume of the devices studied.Keywords
