q-switching definition
Actively Q-switched microchip laser. Tunable etalon (i.e. Fabry-Perot). Active Q-switching by shifting the Fabry-Perot resonance frequency in and out of the microchip axial mode. Etalon resonance shifted with an electro-optical effect. J. J. Zayhowski et al., Opt. Lett. 20, 716, 1995. 115 ps, 1 kHz shortest pulses with active.
The Q-switched mode locking (QML) regime provides the generation of relatively high peak power picosecond pulses train with energies of a few µJ each in a simple resonator. The critical review of QML methods and results including our investiga- tions is given in the first part of presentation. The application of several
Q-switching. In order to store many atoms in an upper level, the flow to a lower level must first be limited. Thus, stimulated emission must be prevented by placing an attenuator in the cavity to stop light from travelling back and forth (note: this attenuator is usually a light modulator, rather than a mechanical shutter, which

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

Abstract: The Q-Switched Mode Locking (QML) regime provides the generation of relatively high peak power picosecond pulses train with energies of a few µJ each in a simple resonator. The fully modulated efficient QML regime was demonstrated in the diode pumped Nd:YVO4 laser. The acousto-optic cell playing a
