Abstract :
An estimation of the linewidth enhancement factor α for a PbCdS diode laser is reported. The measurement method, which is an extension of an earlier procedure involving studies of mode spectra, was devised particularly for this lead-salt diode laser of very low output power. A quite low α of 1.3 was obtained, well below the values for other types of diode lasers
