Advances in Two-Photon Microstructuration of Polymers, Proteins and Metallic Materials with Q-switched Microlasers
Patrice L. Baldeck, Teodora Scheul, Jocelyne Bosson, Monica Iosin, Chih-Lang Lin, Guy Vitrant and Olivier Stephan

Two-photon induced photochemistry localized at the focal point of subnanosecond laser pulses is used to fabricate tri-dimensional micro-objects made in polymers, noble metals, and biological materials. Two-photon cross-linking of proteins and polymers is obtained with Q-switched Nd-YAG laser at the 532-nm wavelength. Two-photon reduction of silver nitrate is obtained with the 1064-nm wavelength.

Keywords: Two-photon absorption, microfabrication, polymers, proteins, metal, microlasers.
