Problems solved by technology
At present, the laser plasma mirror is usually used as the cavity emptyer. This type of cavity emptyer requires a strong laser, so the system is complex and expensive; in addition, the laser plasma mirror located in the resonator inevitably consumes the power in the resonator, which affects The resonant cavity saturates the pulse energy, reducing the output pulse energy

The invention discloses a high-pulse-energy resonant cavity type free electron laser system which comprises an electron source for generating electron beams, an electron accelerator arranged on an electron beam path behind the electron source and used for accelerating the electron beams, and an undulator arranged behind the electron accelerator and used for generating radiation pulses through theelectron beams. Resonant cavities used for oscillating radiation pulses back and forth and amplifying radiation pulse energy are arranged at the two ends of the undulator, cavity emptiers used for pouring saturated radiation pulses in the resonant cavities out of the resonant cavities are arranged in the resonant cavities, and laser pulses generated by the system are high in energy and have the advantages of being narrow in bandwidth, wide in frequency coverage range, continuously adjustable and the like. Meanwhile, the construction difficulty and the construction cost are low, and popularization is facilitated.
Description
technical field [0001] The invention belongs to the technical field of lasers, in particular to a high pulse energy resonant cavity type free electron laser system. Background technique [0002] The resonant cavity free electron laser uses free electrons as the medium to amplify the radiation pulse in the resonant cavity, and couples the saturated laser pulse to the outside of the resonant cavity through a small hole. It has the advantages of narrow bandwidth and continuously adjustable frequency. However, the conventional resonator-type FEL pulse energy is limited by its coupling output mode, and can only output a small part of the saturation pulse energy in the resonator, resulting in a single pulse energy generally at most tens of microjoules. [0003] Cavity emptying technology was proposed in the 1960s. After the radiation pulse energy in the resonant cavity is saturated, this technology outputs the saturated radiation pulse out of the cavity at one time, which can almo...
