Modal analysis of laser vibrated structures

This thesis describes the laser irradiation of metallic structures to excite mechanical vibrations within those structures. As found by other authors, single high-power laser pulses ablate the irradiated surface material and may impulsively excite structural vibration; however, the use of laser power densities above the ablation threshold causes significant surface damage. This work extends current optical excitation techniques by demonstrating that a single laser pulse, with a power density below the surface ablation threshold, can also efficiently induce flexural vibration in a structure.
