Beschreibung
Zusammenfassung:	The proposed method and device relate to acousto-optics and laser technology and can be attributed, in particular, to acousto-optical (AO) laser resonator Q-switches, AO devices for extra-cavity control of single-mode (collimated) and multimode (uncollimated) monochromatic and non-monochromatic laser radiation, i.e, AO modulators, AO frequency shifters, and dispersion delay lines for visible and middle IR wavelengths (0.4-5.5 μm). The object of the method and device is providing a geometry of AO interaction in laser resonator Q-switches so that to optimize the preset parameters of the Q-switch in accordance with the system requirements to the laser operation mode depending on the intended use of the laser, more specifically, lower control RF power and capability of operation without additional efficiency loss with multimode or uncollimated laser radiation.
