AI总结:

本文研究利用主动能量压缩获得极低能散的激光等离子体加速器电子束,并通过激光调制使其在约100次谐波处产生稳定、可调谐的窄带相干辐射,为未来等离子体设施提供新能力。

摘要:

目前正在研究用于未来激光等离子体加速器的主动能量压缩方案。该方法能够产生相对切片能散极小的激光等离子体加速器电子束,约为 $\sim 10^{-5}$。当受到激光脉冲调制时,此类电子束可以在调制激光波长的极高次谐波(约 $\sim 100$ 次)处产生相干辐射,而传统技术难以获得这些谐波。该方案有潜力通过产生稳定、可调谐的窄带辐射,为未来基于等离子体的设施提供额外能力。

英文摘要:

Active energy compression scheme is presently being investigated for future laser-plasma accelerators. This method enables generating laser-plasma accelerator electron beams with a small, $\sim 10^{-5}$, relative slice energy spread. When modulated by a laser pulse, such beams can produce coherent radiation at very high, $\sim 100$-th harmonics of the modulation laser wavelength, which are hard to access by conventional techniques. The scheme has a potential of providing additional capabilities for future plasma-based facilities by generating stable, tunable, narrow-band radiation.
