Special Session (L1) "Hybrid femtosecond laser manufacturing"

Prof. Ya Cheng (Shanghai Institute of Optics and Fine Mechanics, Chinese
Academy of Sciences, China)
Short Description:
The new frontier in 3D Femtosecond (fs)
laser micromachining is the combination of different additive and subtractive
processes to increase the performance of this manufacturing tool. Different
femtosecond laser micromachining processes have been separately developed, from
waveguide and microchannel fabrication, two-photon polymerization, to laser
ablation and texturing. Each of these individual approaches has its own
limitations, therefore their combination into an hybrid approach will help
enhancing the flexibility/capabilities of fs micromachining by taking the
advantages of complementary characteristics of each single approach. The aim of
this special session will be to highlight the latest achievements in each
fs-laser-micromachining process, and to show how the combination of different
fs-laser manufacturing processes can produce a synergic enhancement of the
achieved results, enabling breakthrough applications in novel and promising
research areas.
The topics of this special session
include:
- Fabrication of microfluidic devices by
femtosecond laser micromachining.
- Femtosecond laser direct write methods to
modify and microstructure materials in three dimensions.
- 3D multiphoton polymerization.
- Hybrid femtosecond laser microfabrication to
obtain glass and polymer composite devices.
- Combination of distinct femtosecond laser
material processing techniques to fabricate innovative devices, in fields like
integrated optics, MEMS and microfluidics.

Special Session (L2) "Near-field nanopatterning"
Session Organizers:
Dr. Philippe Delaporte
(Aix-Marseille University, France)
Dr. Mitsuhiro Terakawa
(Keio University, Japan)
Short Description:
The use of
self-assembled microsphere monolayers promotes a wide variety of methods for
the fabrication of nano-periodic structured materials. They represent a mask
for the deposition of periodic nanostructures, and they also can be used for
near-field lithography since each sphere produces a sub-wavelength light spot
when illuminated by a planar wave, thanks to the field enhancement in the
vicinity of the sphere. Over the last decade, this approach has yielded the
development of new laser nanofabrication processes for 2D nanostructured
materials or sphere patterning. All the physical mechanisms associated with
these novel laser processes and their applications are covered by this session,
including:
- Laser microsphere interactions for
nanopatterning
- Sphere manipulation and near-fied processing
- Characterization and modeling of field
enhancement
- Applications (drug delivery, biosensors,
plasmonics)

Special Session (L3) "Laser synthesis and excitation of
nanoparticles"
Session Organizers:
Prof. Dr. Stephan
Barcikowski (University of Duisburg-Essen, Germany)
Prof. Michel Meunier (École
Polytechnique de Montréal, Canada)
Prof. Hiroyuki Wada
(Tokyo Institute of Technology, Japan)
Short Description:
Laser synthesis and
ablation in liquids has proven to be a unique and efficient technique to
generate, excite, fragment, and conjugate metal, alloy, semiconductor, ceramic,
and organic nanoparticles. This session aims bringing researchers together
working of fundamentals and application in the fields of "Lasers &
Liquids" as well as "Lasers & Nanoparticles" (e.g., see
http://youtube.com/nanofunction). Accordingly, topics will cover formation
mechanism, spectroscopy and process efficiency as well as applications in
catalysis or biomedicine.
Pulse laser excitation
induces not only ablation of solids but also fragmentation, melting, and
annealing, which results in the unique properties of the generated
nanomaterials. In the bio-field, upconverting or plasmonic properties are
increasingly investigated as novel bioimaging and nanosurgery tools. In this
session, the recent advancements and critical aspects in the fields of both
laser synthesis and laser excitation of nanoparticles will be discussed at
LPM2015.
