Effect of detuning on the fluctuation properties of a laser.
Detuning the cavity of an inhomogeneously broadened laser has the effect of changing the fluctuation properties of the light in a way that cannot be expressed simply by making the laser gain or the pump parameter frequency dependent. The relative intensity fluctuations are an explicit function of detuning. This is demonstrated by photoelectric counting measurements of a He-Ne laser. The effect may have to be taken into account in some experiments because it is common practice to vary the working point of such a laser by detuning.
