About
I am a consultant specializing in
laser damage resistant optical
coatings. I have extensive
experience as a physicist and optical
engineer, with BS and PhD degrees in
physics, SPIE and Optica (formerly
Optical Society of America) senior
memberships, and 50+ scientific
publications. My expertise in
laser damage resistant optical
coatings is based on my experience at
Sandia National Laboratories where,
from 2004 to 2017, I designed and
produced optical coatings for the
meter-size optics of Sandia’s
petawatt-class Z-Backlighter high
energy lasers. I was a distributor for
OptiLayer Thin Film Software from 2017
to 2022.
