TL;DR

This paper proposes a novel x-ray Raman compression method utilizing two-stream instability in dense plasmas, significantly reducing the required pulse intensities compared to traditional schemes.

Contribution

It introduces a new Raman compression scheme for x-rays driven by beam-induced Langmuir waves, lowering intensity requirements by over two orders of magnitude.

Findings

Seed and pump pulse intensities can be reduced by over 100 times.

Applicable wavelength range is 1 to 10 nm.

Potential for more efficient x-ray compression in dense plasmas.

Abstract

A Raman compression scheme suitable for x-rays, where the Langmuir wave is created by an intense beam rather than the pondermotive potential between the seed and pump pulses, is proposed. The required intensity of the seed and pump pulses enabling the compression could be mitigated by more than a factor of 100, compared to conventionally available other Raman compression schemes. The relevant wavelength of x-rays ranges from 1 to 10 nm.
