Q-switching, sometimes known as giant pulse formation or Q-spoiling, is a technique by which a laser can be made to produce a pulsed output beam. The technique allows the production of light pulses with extremely high (gigawatt) peak power, much higher than would be produced by the same laser if it were operating in a continuous wave (constant output) mode. Compared to modelocking, another technique for pulse generation with lasers, Q-switching leads to much low… WebPulsed Lasers are available in wide range of pulse widths from femtosecond through millisecond. The repetition rates range from single shot to Mhz. Active Q-Switched Lasers allow the precise control of both the pulse width and repetition rate of the laser using an on / off system of blocking or emitting photons.
