Influence of the spectral properties of a wavelength-modulated laser diode on the resulting interferogram

The spectral behaviour of a laser diode during its modulation was investigated in order to find the correlation between the spectral properties of a light source and the appearance of an interferogram resulting from its radiation. The expected fringe visibility curves for a laser diode working in a stable as well as in "mode hopping" regions are given. The experimentally obtained interference patterns which visualise such effects as wavelength shift and coherence collapse are also presented.
