Coherent Light Coherence is one of the unique properties of laser light. It arises from the stimulated emission process which provides the amplification. Since a common stimulus triggers the emission events which provide the amplified light, the emitted photons are "in step" and have a definite phase relation to each other. With a classical slit spectrograph, calibration is done by injection through a fine entrance slit (some microns of wide) of light from a lamp containing a gas having emission spectral lines. Since those lines' positions are well known, it becomes possible to link pixels numbers to wavelengths (in first approximation the relation is a linear one).
