Abstract
Ultrafast laser stress figuring (ULSF) is a figuring process that can deform optical substrates using ultrafast laser generated stress. This technique would be a valuable tool in the mirror substrate manufacturing process if it can be predictably applied to a wide range of substrate geometries and surface height errors. This work explores the simulation of the capabilities of ULSF using Monte Carlo analysis with nonlinear optimization of corrected RMS surface height error.

Currently completing a Mechanical Engineering MS at the University of Arizona with a concentration in Solid Mechanics, being advised by Dr. Brandon Chalifoux. Research topics include: structural mechanics of thin film optics and predictive modeling and correction of spatial frequency errors in optical substrates using ultrafast laser stress figuring (ULSF). I graduated from the University of Arizona with a B.S. in Mechanical Engineering in 2022.
