METHOD AND DEVICE FOR LASER RADIATION MODULATION

The present invention relates 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 IRwavelengths (0.4-5.5 mum). The object of the present invention 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. 本发明涉及声光技术和激光技术，尤其涉及声光(AO)激光谐振器Q开关(Q-switch)，用于单模(准直)和多模(非准直)的单色和非单色激光辐射的腔外控制的AO装置，即，用于可见光波长至中红外波长(0.4-5.5μm)的AO调制器、AO移频器和色散延迟线。本发明的目的是提供激光谐振器Q开关中的声光(AO)相互作用的几何结构，从
