Paper Abstract
Laser shock micro-forming is a non-thermal laser forming method that use laser-induced shockwave to modify surface
properties and to adjust shapes and geometry of work pieces. In this paper, we present an adaptive optical technique to
engineer spatial profiles of the laser beam to exert precision control on the laser shock forming process for free-standing
MEMS structures. Using a spatial light modulator, on-target laser energy profiles are engineered to control shape, size,
and deformation magnitude, which has led to significant improvement of the laser shock processing outcome at micrometer
scales. The results presented in this paper show that the adaptive-optics laser beam forming is an effective method
to improve both quality and throughput of the laser forming process at micrometer scales.
