This lab performs nanomachining research
using femtosecond lasers. Results indicate that femtosecond
lasers can remove nanolayers of material during a single pulse.
In order to observe the nanomachining process research is conducted
in a Philips Environmental Scanning Electron Microscope (FEI
ESEM). The University of Nebraska is in the process of building
a class 100 clean room facility for conducting nanotechnology
research and the fabrication of nanodevices. Research is being
funded by Advanced Micron Devices(AMD) to detect nanosize particles
on silicon wafers using femtosecond laser second harmonic detection
methods. Sandia National Laboratories sponsors research on the
cutting of MEM devices. NASA sponsors research on the use of
femtosecond lasers to cut samples being returned from various
space mission e.g. aerogel materials return from space containingdust
from the tail of the comet. A Ti-Sapphire femtosecond laser
nanomachining system is shown in the figure.
