PEV Series VUV Laser Source (114nm Wavelength, 11eV Photon Energy)


(Reservation Now Open for 2022 Delivery)


Product Overview

PEV Series is a vacuum-ultraviolet (VUV) coherent light source specially designed for excitation light source for photoelectron spectroscopy (PES) applications. Based on OXIDE’s deep-ultraviolet laser technology, the VUV light source has been developed.
By integrating the VUV light source with an Angle-Resolved Photoemission Spectroscopy (ARPES) and TOF analyzer for example, new material development tools to develop such as battery materials and nanomaterials can be built. It can also contribute to realize entirely new laser photoelectron spectrometer.



  • OXIDE’s 11eV laser output is coherent thus can be focused on the target sample with a single lens (micro focus option available).
  • By integrating all the optics into one unit, adjustment of the equipment on-site is not required. Thus, the lead time from the delivery of the equipment to start photoelectron spectroscopy can be shortened.
  • PEV Series VUV Laser Source is highly reliable with industrial quality while it is intended for research applications.
