Exempel på hur man kan använda Q-SWITCHING i en mening

• 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 first pair of applications, filed together in April 1959, covered lasers based on Fabry–Pérot optical resonators, as well as optical pumping, pumping by collisions in a gas discharge (as in helium–neon lasers), optical amplifiers, Q-switching, optical heterodyne detection, the use of Brewster's angle windows for polarization control, and applications including manufacturing, triggering chemical reactions, measuring distance, communications, and lidar.
• By pulsing the discharge using higher voltages, or Q-switching using a rotating mirror, pulse powers of a few kilowatts could be obtained as a practical limit.
• He investigated, in addition to photoluminescence of organic molecules, the photophysics of saturable absorbers (cryptocyanine and related dyes, then used for passive Q-switching of ruby lasers), and used their nonlinear behaviour for determining the subnanosecond lifetimes of their first excited singlet states.
