Abstract
With the exception of very small lasers having extremely short resonators, the typical pulse width obtained from a Q-switched laser is on the order of 10–20 ns for most systems. With the cavity dumping technique, the pulse width can be reduced to a minimum of 1–2 ns. The limitation here is the length of the cavity, which determines the pulse length. Ultrashort pulses with pulse widths in the picosecond or femtosecond regime are obtained from solid-state lasers by mode locking. Employing this technique, which phase-locks the longitudinal modes of the laser, the pulse width is inversely related to the bandwidth of the laser emission.
