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.
