are locally ionized because of the high-energy light interaction with material, they are
passed to the mass spectrometer for identification. By this means, spatially resolved
analysis with micrometer resolution is possible in complex samples, such as melt inclusions, dust aerosols, zonations of minerals,
ultrathin films, and biological samples.
Apart from the above-mentioned advan-
tages, femtosecond laser pulses were also
shown to reduce the matrix effect and ele-
mental fractionation, which might nega-
tively influence the quality of analysis.
Femtosecond laser-assisted mass spec-
trometry systems are already commercially available, and the technique itself
has considerable potential to be routinely
used for in situ analysis of element and
isotopic compositions for a wide variety
These are exciting times for femtosecond
laser applications in high-quality material
processing, with many new applications
emerging daily. High efficiency, elimina-
tion of HAZ, and applicability to many different materials are the key driving factors
in this field.
On the laser source side, this drives
additional parameter flexibility require-
ments, permitting the user to fine-tune the
light-matter interaction recipe for the highest efficiency and quality. ✺
