The development of new methods for generating pulsed electromagnetic microwave radiation is currently an actively developing area of research. Schemes for microwave radiation generation with optical pumping are of great interest. In this paper we propose and experimentally demonstrate principally new method for photonic generation of microwave electromagnetic radiation. This method is based on the use of radiation of charged submicron particles oscillating at their own acoustic frequency. Laser radiation of the optical range implements an effective buildup of acoustic vibrations of submicron particles forming the system under study, according to the Raman mechanism.
目前,用于产生脉冲电磁微波辐射的新方法的开发是一个积极发展的研究领域。利用光泵浦产生微波辐射的方案备受关注。在本文中,我们提出并通过实验证明了一种用于微波电磁辐射光子产生的全新方法。该方法基于利用以自身声频振荡的带电亚微米粒子的辐射。根据拉曼机制,光学波段的激光辐射可有效增强构成所研究系统的亚微米粒子的声振动。
