Tunable High-Harmonic-Generation between 25 and 50 eV exploiting a versatile OPCPA driver laser

We present a versatile high repetition rate, optical-parametric chirped-pulse amplifier system (OPCPA) in combination with a high-harmonic-generation (HHG) source. Tuning of the fundamental OPCPA driver wavelength allows for high harmonic generation within the full range between 25 and 50 eV. All energies between two adjacent odd harmonics can be addressed, making the system a powerful, gaplessly tunable extreme-ultraviolet (XUV) light source for spectroscopy.

Automated summary

This article presents a versatile high repetition rate optical-parametric chirped-pulse amplifier system, coupled with a high-harmonic-generation source. By tuning the driver wavelength, high harmonic generation can be achieved in the range of 25 to 50 eV, allowing for control and tuning of all energies between adjacent odd harmonics. This makes the system a powerful and gaplessly tunable extreme-ultraviolet light source for spectroscopy.
