LPM2019 Special Sessions

Rev. Nov-6-2018-002

1) "Laser synthesis and processing in liquidsh

 

Session Organizers (alphabetical):

Tsuyoshi Asahi (Ehime University, Japan); Stephan Barcikowski (University of Duisburg-Essen, Technical Chemistry and Center for Nanointegration Duisburg-Essen CENIDE, Germany); Changhao Liang (Chinese Academy of Science, Hefei, PR China); Myong Yong Choi (Gyeongsang National University, South Korea); Katharine Tibbetts (Virginia Commonwealth University, USA)

 

Short Description:

Lasers and liquids form a beautiful liaison: Laser synthesis and processing of colloids is an emerging field, including laser ablation, photochemistry, fragmentation, and melting in liquid to create nano- and submicron particles with unparalleled properties. Application of laser-made nanoparticle building blocks has recently approached commercialization in the field of catalysis, and first successful in vivo bio-applications have been demonstrated. In addition, fundamental studies to discover the underlying particle formation mechanisms drive this comparably young field. You are highly welcome to this special session, to present, meet, and vividly discuss the recent progress.

 

 

2) "Laser coloring using short and ultrashort pulsed lasers"

 

Session Organizers:

Andrés Fabián Lasagni (Technische Universität Dresden, Fraunhofer-Institut für Werkstoff- und Strahltechnik IWS, Germany); Bogdan Voisiat (Technische Universität Dresden, Germany)

 

Short Description:

Producing variable information marking elements with lasers, has shown to be an important application field in marking industry. In particular, laser processing with short and ultrashort pulsed laser sources has been already used to produce a large variety of decorative elements, safety holograms as well as encrypted information that can be readable using especial devices. This special session focus on the basics and principles of laser based fabrication methods, which permit to produce decorative elements on the surface of different materials. This includes different technologies, such Laser Induced Periodic Surfaces Structures, Spatial Light Modulator processing, Direct Laser Interference Patterning and Interference Lithography between others. Also technologies producing permanent coloration for instance in metals based on oxidation processes will be considered in this session. 

 

 

3) gLaser processing of glass materials: current status, trends and futureh

 

Session Organizers:

Tetsuo Kishi (Tokyo Institute of Technology, Japan); Yves Bellouard (Ecole Polytechnique Federale de Lausanne, Switzerland)

 

Short Description:

The glass is an indispensable material for optics and photonics because of its wide optical window from ultraviolet to infrared wavelength region, various refractive indexes and excellent formability.  Nowadays, laser process using pulse or continuous-wave laser with the various wavelength is used for cutting, welding, melting, or modifying the glass materials to manufacture various kinds of devices. The interaction between laser light and glass has still been an exciting and essential issue in both scientific and technical aspects.  We expect that newest results and new approaches for laser processing of glass materials will be presented and discussed in the special session, including the mechanism of the induced phenomena and the functionalities of resulting devices.
