Abstract
We present a novel design of a hybrid amplification chain for pumping a Sn target producing ∼μJ coherent soft-X-ray pulses at few-Hz repetition rate. The driver aims to generate multi-joule energy at the central wavelength of 1053 nm and consists of optical-parametric chirped-pulse amplification (OPCPA) combined with diode-pumped Nd:YLF amplifiers. The soft-X-ray laser at the wavelength of 11.9 nm is produced by focusing the infrared beam into a line focus on a solid Sn target. Benefiting from this hybrid pump scheme and grazing-incidence pump geometry (GRIP), such a system has the potential to upscale the repetition rate of soft-X-ray lasers from single shot to the few-Hz region.
