Description

From a pioneer in robust, engineered EUV systems.

The good news: you no longer need to devote laboratory resources to building a system for high harmonic generation (HHG). The fourth generation of the KUUAB ™ XUUS ™ Extreme UV ultrafast source is a turnkey system that will take the hassle out of running an experiment. XUUS4 is a coherent EUV / soft X-ray light source based on high harmonic generation. It is a fully integrated commercial source based on a single robust opto-mechanical platform.

XUUS4 converts ultrafast laser pulses into extreme UV (EUV or XUV) or soft X-ray regions of the spectrum. Using HHG processes, the output beam inherits the coherent properties of a guiding laser, such as: KMLabs RAEA, with a wavelength that can be tuned from ~10 to 47 nm. In addition, custom systems can generate coherent beams with wavelengths as short as 6.5 nm. XUUS4 uses KMLabs’ patented hollow waveguide for the high harmonic up-conversion process.

The architecture of the XUUS hollow core or waveguide allows the harmonics generated by the system to be distinguished from other HHG methods, ensuring that the harmonics arise from the same point in space each time, minimizing pointing drift. This optimizes the repeatability of your experiments. In addition, using a fiber instead of the typical gas jet geometry or partially infinite geometry of the target gas cell provides better pressure control for phase-matched HHG. Now you can choose robustness without sacrificing flexibility.
