Output Power and Temperature Dependence of the Linewidth of Single-Frequency cw(GaAl)As Diode Lasers

摘要

We report here the observation of a linear dependence of cw single-frequency (GaAl)As diode laser linewidth as a function of reciprocal output power at 77,195, and 273 K. The observed data are explained in terms of spontaneous emission events and their related refractive index perturbations.
