Seeing and Shaping the Microscopic World
with Multiphoton Absorption

The inherent optical nonlinearity of multiphoton absorption (MPA) allows for the localization of photophysical and photochemical processes within a tight focal volume, the position of which can be controlled in three dimensions. This feature of MPA has led to numerous advances in 3-D imaging and fabrication in recent years.   I will discuss two particular applications of MPA, multiphoton-absorption-induced luminescence for the detection of single nanoparticles and the fabrication of functional 3-D microdevices.
