in which the state of the device introducing important losses in the resonant cavity
and preventing lasing
operation is suddenly switched to a state where the device introduces very low losses.
This increases rapidly the Quality factor of the cavity, allowing the build-up of
a short and very intense laser
pulse. Typical pulse durations are in the ns range. The Q-switching may be active
(a rotating mirror or electro-optic device) or passive (a saturable absorber
