Project: Laser Stability Monitoring
(05/2023)
This is our team's Senior Design Project in Spring 2023. The goal is to identify the drift sources causing at least a 1 μm drift in laser monitors operated by the Laboratory for Laser Energies through FEA simulations and prototype experiments on optical bench.
Project assignment is designed by Professor Christopher Muir. My great team members are Owen Wacha, Gyeongjae (Jay) Yoo, and Makarii Yurkiv. (Team photo)
Optical Bench Experiment: Mach-Zehnder Interferometer
Step 1: Verify the fundamental set-up is efficient.
Examples of fringes recorded from the fundamental set-up: temperature controlled and vibration isolated
Step 2: Design, Manufacture, and Install a kinematic 3-stage platform to hold an optical mirror while an external thermal source is applied.
Rettner Experiment: Michelson Interferometer
Design, Manufacture, and Install a kinematic adapter to hold an optical mirror on a steel beam structure.
Process recorded data using MATLAB
Perform 2D FFT to find angle from vertical.
Calculate fringe spacing from vertical mean image.
Plot calculated angle and fringe spacing from processed data.
Mathematically calculate translational distances and tilt angle of mirrors from recorded data
Analyze drift data from the target chamber during laser shots
Analyze provided drift data
Field visit to acquire thermal images on localized heat sources
FEA on the Target Chamber structure with localized heat sources applied
Possible other factors for future work
