SESSION 1: Setting up the scene

In this session the challenges and applications of the high power lasers were discussed. It was highlighted that as high power laser systems require a current driver the power supply has to be carefully selected to fit all the requirements as it is very system dependent. The selection of the system is also highly application dependent. Surface micro- and nano- structuring becomes increasingly in demand for multiple different applications and this technology requires high speed production and ultrashort pulses of a laser. The multilayer materials can be processed only using femtosecond high power lasers. Furthermore, for the process monitoring and throughput increase e.g. during metal-works the back reflected light could be converted into useful information such as focusing or pierce detection.

SESSION 2: High power and fluence beam shaping solutions

This session discussed importance of the beam shaping and highlighted novel technologies for the beam and system performance control. Some main points of this session were following: (1) Beam shape has a critical role in the interaction of the laser and surface including the final structure of the surface; (2) Surface micro-processing is highly dependent on the beam stabilization and alignment; (3) Homogeneous and stable beam can be achieved using mode cleaning technique; (4) Surface coating of optical components of a high power laser system is crucial to ensure long term high quality performance of the system; (5) Cooling system of the high tower lasers is anothercritical parameter which should not be neglected.

SESSION 3: High power laser-based solutions and needs

The demands and solutions for different parts of the system were addressed. The main points included (1) The importance of parameter such as: operation life-time; photo-darkening; thermal hardening; polymer coatings; etc. for successful design of a high power laser system have to be considered; (2) An efficient solution for different types amplifier – another critical part of the system –can be created through thin disk technology; (3) The heat distribution via beam oscillation can is developed as a new solution, enabling increase in throughput of the system without increase of the power; (4) New materials, such as diamond technology offers yet another solution for heat conductivity.

SESSION 4: The high power laser supply chain

In this session it was shown that opto-mechanical deformable mirrors are excellent solution for wave front correction needs correction of high power lasers and micro or nanopositioning. Further it was discussed that besides different components of the high power laser system the system control end testing plays an important role. It was shown that novel technology for beam profiling via scattering can serve for process improvement as well as predictive manufacturing. Also high power laser system testing such as burn-in test could enable evaluation of the system capability and facilitate laser system reliability in field work.
