2 Real versus virtual world If we look around, more and more virtual reality prevail: life, cars, sea, food, computer-simulated life lifelike experience telexistence Even love Twitter Facebook How all this works? 2

3 Real technical means support its functionality Wire, optical and wireless communication Semiconductor chips and photonics components Signal processing and transfer 3

4 Needs equipment and machinery to realize Mechanical, chemical engineering Photonics tools lasers, as well 4

5 Lasers How to launch a rocket? as a tool Stars war guns by nonlinear time-multiplexing of lasers pulses 5

Nobel price in physics on laser discovery 1966 first laser fired at Vilnius

6 Lithuanian Laser & Photonics ecosystem World-recognized laser & photonics community with a long history 1960 Theodore Maiman discovered the laser 1964 Nobel price in physics on laser discovery 1966 first laser fired at Vilnius University 1970 a laser fired at the Institute of Physics 1983 pilot plant EKSMA was established

7 Lasers: tools for research and production Drift: shift, change of priority Lasers for science Break-through solutions Beyond the limits Lasers for industry Reliability Long-term stability Easy to maintain Low -cost 7

8 What to do else? Back to

9 Pulse duration versus processing quality With a bad tool is difficult to make good things but with a good tool easy to make bad things 3,3 ns 200 fs 500 fs are ps optimal? steel thickness: 0,1 mm diameter: 140 µm LZH steel thickness: 1 mm diameter: 70 µm Is the shorter (pulse), the better? IFSW 20 ns

10 Cutting, drilling, ablation, modification.. and the answer comes from doing simple real things Watch industry Medical: stents Micromechanics Different customers Europe USA, Japan, China, Different materials: Glass, Ceramics, Diamond, Composites, Different applications 10

11 Laser processes in Photovoltaics for thin-film solar cells interconnects ITO Mo for solar light harvesting in crystalline silicon PV CIGS Mo CIGS ITO T l a) b) Δτ L Time, ps 11

12 Thin-film patterning for electronics ITO /glass: for OLEDs ITO on PI: RFID 2,45 GHz Laser-induced local metal plating for Moulded Interconnect Devices THz filters THz Frensel lens 12

13 Multi-beam laser patterning Laser beam interference ablation Si surface nanopatterning DOE SL2 75 mm + sub-period motion + chemistry D SL1 25 mm Metal nanofilms Al + self-organization 50 μm Nanostructures with a period down to 600 nm 13

14 We are developing laser technologies Where is our end-user? Japan, China, USA? how to get feedback? Look Europe! 14

15 Goal of a FP7- ICT - FoF call Reducing barrier to enter into market with new product (equipment for laser-based manufacturing) Equipment supplier preferable SME Laser application lab (HUB) System integrator or end-user Success wanted: new jobs; new factories; new markets

Hub of Application Laboratories for Equipment Assessment in Laser Based Manufacturing FTMC - coordinator www.appolo-fp7.

16 Hub of Application Laboratories for Equipment Assessment in Laser Based Manufacturing FTMC - coordinator Goal of APPOLO: validation of laser based equipment for industrial applications 22 partner from 9 countries Core of the consortium laser application laboratories: around Europe; connected to a virtual hub, in order to accumulate knowledge and infrastructure promote the easy-to-access environment develop and validate of laser-based technologies in 8+ equipment assessment value chains Industrial Advisory Board Input from other assessment chains 36 partner 11 countries 15 sub-projects Assessment procedures Equipment assessment Integration for process validation Equipment in processing Validation with end-user 16

17 APPOLO: Clusters of Activities Thin film CIGS solar cell scribing with picosecond lasers cell N N+1 dead area active area I SC P1 P2 P3 P1 Laser surface texturing Laser patterning and direct writing for flexible 3D electronics Parallel activities on sensing and monitoring techniques for processing and validation 17
