This month's edition of Electro Optics Magazine features an article on the test ethos of BRL and our latest whitepaper on threshold elevation. Gemma Church explains how and why BRL takes a robust and accurate approach to laser damage testing, alongside comments from our CEO Dr Rona Belford on the potential to overtest samples during a laser damage test.
BRL's latest whitepaper expands on the subject of annealing and its influence on accurate determination of laser damage threshold. This whitepaper addresses the threshold elevation that can arise from "over-testing", specifically by using too many laser shots per test site. We report on threshold elevation with increased number of shots per site for different coatings and different substrates with the same coating. The whitepaper can be found here.
Andrew Ritchie has taken up a new position at BRL as an Assistant Physicist and Systems Programmer. Andrew's experience in systems programming and robotics will be used to address a high level of system integration at BRL, enhancing the efficacy of our knowledgeable team of laser damage test experts.
BRL presents "Laser Damage for Optical Coaters" via the Digital Exhibition at SPIE Security + Defence 2020. This virtual demonstration shows exactly what happens to optical samples under test and explains which samples you need for different types of certification. Exciting live footage of samples damaging is presented. It is now available to view on the SPIE website.
This month's Electro Optics Viewpoint presents a short profile of BRL's capabilities as a laser damage test house and highlights the requirement of high LIDT for high power lasers. This Viewpoint, authored by BRL's CEO Dr Rona Belford, also examines the distinct regimes of laser damage and how they pertain to pulsed, CW or ultrafast laser systems.
This month's Electro Optics magazine features BRL's latest whitepaper, "High Power Laser Damage & Annealing - Justification for ISO Standard Recommendations" by Dr Rona Belford and Kieran R Ross. We detail the potential for large scale variance in LIDT values by ignoring important details of the ISO standards. It is now available on the Electro Optics website.
BRL has released a new whitepaper detailing the effects of small parameter changes, deviating from ISO standard laser damage testing. These small changes give rise to inacurate, high results due to annealing. The importance of ISO standards are justified. The whitepaper can be found here.
Electro Optics Magazine has reissued an article by Andy Extance as part of a Tech Focus on Laser Optics. "Coating Techniques Push Laser Component Limits" was first issued in 2018, discussing advances in coating technology and highlighting BRL as a state of the art laser damage test house. Please scroll down to see the entry from 2018. The article can also be found here.
Our recent whitepaper on CW Laser Damage is free to read via the June digital issue of Electro Optics Magazine.
This month's Electro Optics magazine features BRL's latest whitepaper. The whitepaper, "High Power Pulsed and CW Laser Damage, Understanding the differences in Pulsed and CW damage" by Dr Rona Belford, Kieran R Ross and Dr Matthew Duff, details and contrasts pulsed and CW laser damage mechanisms, as well as presenting LIDT results for optical substrates. It is available on the Electro Optics website.
BRL has released a video targeted at optical coaters. We explain what the coater needs to provide in terms of data and sample. We also show videos of both pulsed and CW damage. The demo was originally compiled for the exhibitors showcase at SPIE Photonics Europe 2020. The video can be found here.
BRL has released a whitepaper, detailing and contrasting the differences in Pulsed and CW laser damage. We also dispel some of the common misunderstandings relating to CW Laser Damage and its units. This work was funded by Leonardo Edinburgh, Gooch and Housego Precision Optics and BRL Laser Damage. The whitepaper can be found here.
BRL now offers continuous wave (CW) laser damage testing up to a linear power density of 500 kW/cm. This linear power density will cover more than 95% of the CW market.
Matthew Duff has taken up a new position at BRL as a Laser Physicist.
Kieran Ross has taken up a new position at BRL as a Lead Physicist.
Arran Fernie has taken up a new position at BRL as a Laser Physicist.
This month BRL was included in a feature article in Electro Optics. The article, "Coating techniques push laser component limits" by Andy Extance, discusses the current advances in coating technology and the importance of laser damage testing. It is available on the Electro Optics website.
BRL has co-authored a whitepaper on laser damage in high-power optics with Gooch and Housego. It is available on the Gooch and Housego website. The paper showcases our recent Laser Damage Live videos, which you can find on our media page.
We have just begun a series of videos on live laser damage. These show unusual and dramatic damage events recorded in our labs. Watch it on our media page.
Welcome to our new, revamped website! We hope you find it easier to navigate but please let us know if you experience any issues or have any comments.
Dr Mulholland gave an invited talk on laser damage testing. He gave examples of BRL's work with the Kerr Effect and showcased two new videos taken of live damage events.
BRL exhibited, showing the first live damage videos illustrating beam focussing due to the Kerr Effect.
BRL successfully completed the SMART feasibility project on 2-micron laser damage testing. The project was successful and BRL are taking their concepts a stage further. Much work is still required to gain confidence in the procedures investigated.
BRL exhibited and Dr. R E Belford gave the demo talk Laser Damage Basics.
Dr Kieran Mulholland joined our group full time. He has a PhD in experimental nuclear physics and has previous experience of laser damage techniques.
Sean is responsible for the extensive electronic and sensing equipment in our firing labs.
BRL commenced a one-year SMART feasibility project. Laser damage at 2 microns presents limiting difficulties which make the test both expensive and challenging to execute. This research project approached the problem from a materials based viewpoint and proposed a novel method for performing laser damage testing at 2 microns using an alternative methodology.
Dr Belford presented an invited talk entitled "Laser Damage on optical components".
Multi-wavelength laser damage test bed became active due to the completion of a Scottish Enterprise feasibility project.
