Suppose I have a laser which produces photons only in one exact frequency. In other words, the laser excites only one mode of the electromagnetic field. Then the line width is zero because there isn't a range of excited frequencies (modes).

WebLaser light with a coherence length shorter than the path length imbalance will ideally produce a Lorentzian spectrum with a half width at half max equal to the laser light spectral linewidth (fig.2).
