Optimizing UV Laser Systems: Understanding Laser Damage Mechanisms

Fundamentals of LIDT, LIC, and Optical Fatigue in UV Applications

Ultraviolet (UV) laser systems present unique challenges due to their high photon energy and increased material sensitivity. Optical coatings and substrates operating in the UV are more susceptible to laser damage, contamination effects, and long-term degradation. Understanding these mechanisms is critical to improving system performance and lifetime.

We invite you to attend this 30-minute webinar, Dr. Matthew Dabney, Principal Laser Engineer at Edmund Optics, will provide an overview of UV laser damage mechanisms and their impact on optical systems.

At the end of this webinar, attendees will have a strong understanding of:

  • Laser Induced Damage Threshold (LIDT), including pulsed vs. continuous wave measurements
  • Why Single Longitudinal Mode lasers are used in LIDT testing
  • Why UV wavelengths are more demanding on optical materials
  • Laser Induced Contamination (LIC), common contamination sources, and how LIC leads to damage
  • Optical Fatigue and how it differs from traditional LIDT

Dr. Matthew Dabney

Principal Laser Engineer, Edmund Optics

Matthew S. Dabney spent the first 13 years of his career mastering details of optics at Hyperfine, Inc. He fabricated and qualified most of the optics in the Hubble Space Telescope as well as other space flight optics. Matthew brought his optics and engineering experience with him to the National Renewable Energy Labs (NREL) where he was an optical engineer for 14 years working on laser processing of materials for photovoltaics. In 2017, Matthew took up a position at Cornell University as a facility manager in charge of Confocal laser microscopy and XPS. Matthew started work as a Principal Engineer and R&D manager at Edmund Optics in 2019 where he leads research in laser interactions with materials. Matthew has published over 30 scientific papers on topics ranging from pulsed laser deposition of novel transparent conducting oxides, laser nucleation and growth of Silicon, the safe use of class 4 lasers in industrial settings, to Development of a robust LIDT testbed.
