High repetition rate, photon energy tunable VUV laser
Hyperion VUV – vacuum ultraviolet source

Overview

KMLabs Hyperion VUV – vacuum ultraviolet source provides bright femtosecond pulses at numerous wavelengths across the vacuum ultraviolet (VUV) region, from 6.0 eV (205 nm) to 10.8 eV (115 nm). The discrete tunability of the KMLabs Y-Fi VUV vacuum ultraviolet source enables researchers to study a wide range of materials and materials properties. A simple computer-selected change of photon energy provides a powerful capability, previously only available at a synchrotron; this ability to easily change the laser wavelength can enhance many experiments. For example, in angle-resolved photoemission (ARPES) experiments, this tunability allows researchers to distinguish surface effects from bulk effects. For time-of-flight (ToF) studies of molecules, the tunability can distinguish otherwise identical isomers.
