Title: Laser interaction with materials and its applications in precision engineering
Abstract: In this paper, laser interaction with materials and its applications
in precision engineering are mainly introduced. To further explore
the physics behind laser interaction with materials, it is of much
significance to investigate the mechanisms in the process. First of
all, it is desired to understand the characteristics and principle
of laser. Laser is generated by stimulated radiation, and has excellent
physical properties, such as high monochromaticity, high brightness,
high directivity and high coherence. Meanwhile, it benefits much to
study the dynamic process of interactions and its mechanisms. There
exist both photo-chemical and photo-thermal processes when laser and
materials interact. Furthermore, developing laser application in nanomaterial
synthesis is also an unique area. It is worth further studying the
design and fabrication of nanostructured materials. Last but not least,
it is interesting to explore the specific process and characteristics
of laser processing, which play an important role in advanced manufacturing.
In precision engineering, the tool of laser has also been more applicable
considering its great advantages in microprocessing and nanofabrication.
Several case studies are introduced, which have great potential and
high impact applications, such as ultrafast laser direct writing,
laser micro-lens lithography, laser nanofabrication to break through
optical diffraction limit and hybrid micro/nanostructures with unique
functions fabricated by laser. These studies have triggered intensive
research interests due to their great application prospect.
