We demonstrate the use of high-speed, multiphoton absorption polymerization (MAP) for the fabrication of large-area microfluidic master structures. High-speed fabrication in SU8 without laser-induced damage is made possible by the use of a novel photoacid generator with a high two-photon-absorption cross-section. Master structures fabricated with MAP can be used to produce polydimethylsiloxane ...

Radially polarizing liquid crystal (LC) devices aligned optically were investigated for applications in laser technology. Presently, radially polarized beams are generated through complex laser resonator configurations or buffing of LC alignment layers. Optically aligned LC devices offer several advantages over these methods, including their simple fabrication, low cost, high laser damage thres...

Mesoscopic additive/subtractive material processing (Meso A/SMP) is a solid freeform fabrication technique capable of producing engineering parts in mesoscopic (100 micron to several millimeters) scales. This process integrates silicon processing, electroplating, hot pressing, casting, and traditional machining methods to provide opportunities for 3D layer fabrication and parallel production, a...
