Abstract
The problem of mode locking and pulse forming by means of intracavity FM modulation is, to a large extent, similar to that of AM mode locking described in the previous chapter. Again the problem can be treated either in the time domain or in the frequency domain. The main difference between the results obtained with AM and FM is that for detuning the mode-locking behavior with FM changes asymmetrically when the modulation frequency is detuned. This asymmetry is due to the dispersion of the active medium. In the present chapter we shall consider small detuning, i.e. comparable with the line width, so that the laser remains mode locked. For larger detuning the output signal of the laser changes to an FM laser type of signal which is beside the scope of the present treatment.
