The present application discloses a laser signal modulation system and a CPT Maser atomic clock, which are applied to the field of atomic frequency standards. The system includes an optical signal emission module, a double-pass frequency shift module, an amplitude noise suppression module, and an optical signal modulation module; the double-pass frequency shift module is configured to divide the original optical signal emitted by the optical signal emission module into a first light beam and a second light beam for generating the CPT effect, and perform a double frequency shift operation on the second light beam to obtain a frequency-shifted light beam. The amplitude noise suppression module is configured to obtain the electrical signal corresponding to the combined optical signal of the optical beam modulated by the optical signal modulation module and the frequency-shifted light beam, and obtain an error signal of the double-sideband amplitude value through demodulation processing and differential amplification processing of the electrical signal, and at the same time, based on the error signal, feedback control the modulation depth of the optical signal modulation module at the current moment. The optical signal modulation module performs real-time modulation on the first light beam based on the adjusted depth, thereby effectively reducing the double-sideband amplitude difference.

The micro-drones may form an autonomous, self-sustaining swarm, such that the micro-drones may exit and rejoin the hybrid drone swarm, automatically, optimizing monitoring by allowing at least one micro-drone to be constantly within the hybrid drone swarm around the target without requiring downtime. Additionally, the micro-drones may automatically recharge via at least one solar panel. In addition, the present disclosure may defend a user and / or area from enemy drones or enemy targets using a system of micro-drones.

The present invention discloses a frequency-tunable terahertz gyrotron collector, which belongs to the technical field of terahertz electric vacuum devices and relates to electron cyclotron maser devices. This structure is used for a frequency-tunable terahertz gyrotron developed in a laboratory, and is a component that collects residual electrons and dissipates electron energy in a water-cooling manner. The collector is connected to the rear end of the gyrotron interaction cavity, and includes a cylindrical hollow cavity and outer wall heat sinks. Each heat sink is a straight rib structure and is located on the outer wall of the collector cylindrical cavity. The gaps between adjacent heat sinks serve as cooling water channels. The straight rib heat dissipation structure is combined with a water-cooling inlet. Through the design of a special collection stage structure, the heat exchange area between the collector and the coolant is increased, the water cooling efficiency is improved, and the collection stage temperature is reduced, thereby improving the stability of the gyrotron operation and ensuring the service life of the gyrotron.
