High-power laser interactions with nanostructured materials

We use short-pulse high-power lasers to selectively modify the structure of nanolaminates and nanocrystals. It is demonstrated that femtosecond pulses can achieve excellent results for microscopic thin film removal. Laser pulses can also be used to modify the crystal structure of thin films. It is a...

Description
Summary:We use short-pulse high-power lasers to selectively modify the structure of nanolaminates and nanocrystals. It is demonstrated that femtosecond pulses can achieve excellent results for microscopic thin film removal. Laser pulses can also be used to modify the crystal structure of thin films. It is also demonstrated that coherent laser excitation promotes a selective modification of nanocrystals, resulting in changes of size, shape, and crystal structure.
