... such that L = Nλ/2, when N is an integer known as the mode order. In practice, the separation distance of the mirrors L is usually much greater than the wavelength of light λ, so the relevant values of N are large (around 105 to 106). Of more interest is the frequency separation between any two adja ...

Mode-locking
Mode-locking is a technique in optics by which a laser can be made to produce pulses of light of extremely short duration, on the order of picoseconds (10−12 s) or femtoseconds (10−15 s).The basis of the technique is to induce a fixed-phase relationship between the longitudinal modes of the laser's resonant cavity. The laser is then said to be 'phase-locked' or 'mode-locked'. Interference between these modes causes the laser light to be produced as a train of pulses. Depending on the properties of the laser, these pulses may be of extremely brief duration, as short as a few femtoseconds.
