Show abstract. WebQ switching is a method for generating intense short pulses (sometimes called "giant pulses") of light with a laser.The basic principle is as follows: In a first phase, the gain medium is pumped, while the extraction of energy as laser light is prevented by keeping the resonator losses high (that is, the Q factor is kept low). This can be done with active or …
