在这里，我们探索使用激光驱动等离子体波将激光辐射转化为不相干和相干电磁辐射的方法。我们提出了几个基于激光尾场加速器 (LWFA) 的示例，并表明与传统设备相比，LWFA 的电子束和辐射具有几个独特的特性。我们表明，在 130-150 MeV 时，能量扩散可以远小于 1%。这使得 LWFA 成为科学家对受刺激的物质进行时间分辨探测的有用工具。它们也是出色的成像工具。我们提出的实验证据表明，由于电子束的持续时间为几飞秒，短至 30 fs 的超短 XUV 脉冲是由 LWFA 驱动的波荡器直接产生的。通过将电子能量扩展到 1 GeV，并持续 1-2 fs，可以产生每 pC 数 MW 的 2 nm 辐射峰值功率脉冲。更高电子能量下增加的电荷将峰值功率提高到 GW 水平，使 LWFA 驱动的同步加速器成为极其有用的光源，其光谱范围延伸到水窗口。随着使用 LWFA 驱动辐射源所带来的尺寸减小，以及预计激光稳定性和重复率方面的进步，超短脉冲辐射源应该变得更加便宜和广泛使用，这可能会改变科学研究的方式。
Here we explore ways of transforming laser radiation into incoherent and coherent electromagnetic radiation using laserdriven plasma waves. We present several examples based on the laser wakefield accelerator (LWFA) and show that the electron beam and radiation from the LWFA has several unique characteristics compared with conventional devices. We show that the energy spread can be much smaller than 1% at 130-150 MeV. This makes LWFAs useful tools for scientists undertaking time resolved probing of matter subject to stimuli. They also make excellent imaging tools. We present experimental evidence that ultra-short XUV pulses, as short as 30 fs, are produced directly from an undulator driven by a LWFA, due to the electron bunches having a duration of a few femtoseconds. By extending the electron energy to 1 GeV, and for 1-2 fs duration pulses of 2 nm radiation peak powers of several MW per pC can be produced. The increased charge at higher electron energies will increase the peak power to GW levels, making the LWFA driven synchrotron an extremely useful source with a spectral range extending into the water window. With the reduction in size afforded by using LWFA driven radiation sources, and with the predicted advances in laser stability and repletion rate, ultra-short pulse radiation sources should become more affordable and widely used, which could change the way science is done.
