Abstract: It is shown that for an average output power of 60 mW, the spectral density of low-frequency intensity fluctuations in single-mode semiconductor lasers lies in the interval 6 × 10^-17 – 10^-15 W² Hz^-1. This fluctuation level is caused by the presence of subthreshold longitudinal modes and mode hopping, leading to the emergence of a noticeable 1/f component in their spectrum.
