Laser Peen Forming with Femtosecond Laser
Journal of the Japan Society for Precision Engineering, 2009 A femtosecond laser is a type of ultrashort pulse laser. A focused femtosecond laser pulse induces high-pressure plasma and a shock wave at the surface of a target. In some cases, this shock wave is enough to deform the target plastically. Laser peen forming is a type of sheet metal forming using this deformation by shock wave.
