by Sarah Diggs
Sarah is a leading authority on technical training and process improvement for the photonics industry. She has successfully developed and launched technical training courses and certification programs for the photonics industry since 1999 and her Laser Technology Series program currently has more than 10,000 corporate trainees on-course via corporate intranet learning systems. Some of her clients include Spectra-Physics, Coherent, KLA-Tencor, Carl Zeiss Meditec, JDS Uniphase, Lightwave Electronics, SPIE, NASA, The Boeing Company, Northrop Grumman, Wylie Labs, Canesta, Rockwell Collins, the USMC, and the USAF.

Sarah began her career in 1986 as a co-op student working in the Solid State Laser Materials Lab at the NASA Langley Research Center, where she was part of the team that developed titanium-doped sapphire as a laser medium. She has also held research and management positions at The Analytic Sciences Corporation (TASC), where she worked at Brooks Air Force base on eye-damage studies and laser-eyewear development, and Lightwave Electronics as a manufacturing supervisor of diode-pumped solid state lasers. In 1999, Sarah started a training company to help Silicon Valley laser manufacturers train their technical workforces in the fundamentals of lasers and optics, including optics inspection, handling, and cleaning, optical alignment, and geometric optics. Her newest venture is a consulting firm that helps photonics companies improve their bottom lines through corporate audits of critical processes and implementing in-house certification programs.

Sarah received degrees in applied physics from Old Dominion University (Hampton, VA) and the University of Texas (San Antonio, TX), and in philosophy from DePaul University (Chicago, IL). Sarah is also a CAT I and CAT II certified laser safety officer.

Now that we have clean optics . . . we need to know how they work!

The assumption is . . . if you work with optics, you obviously know how they work. As crazy as it sounds, this is often not the case. For years I've given a pretest to every student I've ever taught for two primary reasons: first, if I know what...

Certification Matters

It’s time to throw our hats over the fence and institute an optics-inspection, handling, and cleaning certification program for our industry. The Laser Institute of America has established a Board of Laser Safety http://www.lasersafety.org/index.php to...

How to clean optics . . . correctly.

In my last blog, we discussed my cleaning methodology. In this posting, I'm going to detail how to perform each of the four methods, step by step. I've taught these techniques for over a decade to most all of my clients, and many of them run my...
