Fiberlaserens udvikling - oversigt, anvendelser, markedet
Flemming O. Olsen, professor, DTU Mekanik
Laserteknologi har de sidste 30 år vundet stor indpas i industrien. Medens der i de sidste 20 år primært har været en stor udvikling af teknologier og udstyr, har de enkelte lasertyper stort set været de samme.
Skæring i metalplade, det største marked, har været domineret af CO2-lasere. Gravering – et andet meget stort marked, har primært været domineret af Q-switched ND-YAG-lasere. I svejsning, et tredje stort marked, har ND-YAG-lasere i en årrække konkurreret med CO2-laseren.
Men – for ca. 5 år siden dukkede et nyt firma og en ny laser op på scenen: IPG, der på forbløffende kort tid opskalerede fiber-laseren fra mikrowatt til kilowatt.
Denne laser har rystet hele branchen og en kraftig udvikling er gået i gang. Firmaerne, der den ene dag påstod, at fiber-laseren næppe var en realistisk mulighed, møder den næste dag op på lasermessen og viser deres nyeste skud på stammen: Fiber-laseren.
I foredraget fortælles om udviklingen, teknisk såvel som markedsmæssigt, og forskellige markedsscenarier skitseres.
Flemming O. Olsen har via forskning, undervisning, industrisamarbejde og patenter fulgt udviklingen inden for laserområdet i mere end 25 år.
10:10-10:40
High Power PCF-based Fiber Laser Module
Mads H. Soerensen, Crystal Fiber A/S
High-power fiber lasers have gained tremendous momentum in the last five years, and many of the traditional manufactures of gas and solid-state lasers are pursuing the attractive fiber-based systems, which are now displacing the old technology in many areas. High-power fiber laser systems require specially designed fibers with large cores and good power handling capabilities – requirements that are all met by the airclad fiber technology.
The presentation highlights results on the performance of the Crystal Fibre aeroLASE350, which is the first commercially available high power fiber laser module based on Photonic Crystal Fiber (PCF) technology. In the present talk many of the building blocks needed to build high-power systems are presented, including the performance of the aeroLASE350 with respect to efficiency (>60 %), output power (>350 W @ 1064 nm) and beam quality (M2<1.1).
Keywords: Airclad fibers, photonic crystal fibers, high-power fiber lasers
Mads Hoy Soerensen received the M. Sc. in Physics from the University of Aarhus in 2000.  He is currently working as research scientist at Crystal Fibre A/S, Denmark.

Fibre based beam delivery systems, development, possibilities and limits
Magnus Pålsson, Optoskand AB
Fiber optic beam delivery systems are today commonly used with high-power, high-brightness lasers. Besides the fiber optic cable itself, there is a great interest in fiber-to-fiber coupling units making it possible to couple the laser beam between different fibers, either to time share or energy share the laser source between different work stations. The rapid progression of the fiber laser technology has truly challenged the manufacturers of the fiber optic beam delivery components.
This presentation will give an overview of the state-of-the-art fiber optic beam delivery components for high-power, high-brightness lasers on the marked today. What are the limitations today and what demands do we see driving our future development.  
Magnus Pålsson is the Sales & Marketing Manager at Optoskand AB in Sweden. He received a M.Sc. in Physics from Faculty of Engineering at Lund University in 2004.

11:30–12:00
Fiber laser technology for industrial metal cutting
Enrico Fralosso, Chief Export Sales & Marketing Dept., Finsomac Srl, Italy
The fiber laser technology opens new frontiers in the industrial metal cutting processes. Lower energy consumption, less maintenance and less general costs together with a very simple and user-friendly machine are the keys for the next future. FINSOMAC SRL talks about its experience and is proud to introduce you to the CY LASER systems.
Enrico Fralosso - Chief Export Sales & Marketing Dept. - working in Finsomac Srl since 1991 - he's in the Cy Laser staff project since the beginning following its development and keeping contacts with the public outside of Italy.

Fiber laser – the state of the art laser technology
Dr. Jörg Thieme, European Sales & Marketing Manager, IPG Laser GmbH
Updated 1st september to presentation by Dipl.-Phys. Bertold Kessler.
Advanced fiber lasers generate diffraction limited beam quality at highest power levels. Due to the usage of single emitter pump diodes the lifetime is extraordinary high. Beam Quality and power are the first time in the laser technology scalable. The same laser can be used for cutting, welding, brazing and cladding, e.g. 6kW fiber laser can operate at 50µm (<2.5mmx mrad) fiber but also at 100µm (<4.5mm x mrad) up to 800µm. Single Mode Lasers (0.35 mm x mrad) achieve meanwhile >5kW in power.  
Efficiency, compactness and mobility are important factors for industrial
applications.
An overview about applications in micro and macro fields are given.

Laser welding of polymers – Colorants and Additives
Dr. Sibylle Glaser, Leitung Entwicklung/Head R&D, TREFFERT GmbH & Co. KG
In the last couple of years, laser welding of polymers has been a growing field in research and development. The first additive for laser welding was carbon black resulting in a limitation in colour. Due to the development of special additives, the number of possibilities in colour design increased, first for opaque and now for transparent colours also.
Common colorants especially pigments can absorb resp. reflect the laser light limiting their use in IR-transparent preparations. Treffert has developed a great number of colour recipes for these kind of applications resulting in a great expertise in laser welding.
Sibylle Glaser received her diploma in chemistry from the Technical University Kaiserslautern (Germany) and her PhD from the BTU Cottbus (Germany). She worked as a post-doc in the group of Dennis Smith, jr. at Clemson University (SC, USA) in the area of chemical analysis of polymers. In May 2005 she joined the Treffert group polymer technology where she specialises on colorants and additive formulations for laser welding and laser marking of polymers.

Lasersvejsning af plast i praksis
Erik Laursen, Manager Welding and Assembly, Danfoss A/S, Global Service - Technology
I Danfoss teknologicenter har vi løst opgaver med svejsning af plast fra ide til produktion. I indlægget vil vi fremlægge hvad vi har anvendt af laserudstyr til test, hvordan vi har bygget vore test fixture, hvilket laserudstyr vi har hjemkøbt til produktion og hvordan vi har opbygget produktions maskinen. Vi vil også komme lidt ind på vore erfaringer med krav til materialerne som skal svejses.
