Laser Ignition Conference

20 June 2017 – 23 June 2017 Novotel Bucharest City Centre Hotel, Bucharest, Romania

Laser Ignition Conference is an international forum for discussion on various aspects of laser-induced ignition, including novel giant-pulse micro-lasers, measurements and characterisation of plasma induced by laser ignition, new phenomena of laser breakdown or advanced combustion systems, packing of laser systems for harsh combustion environments and their applications. The purpose of this meeting is to share information on laser ignition and related sciences and technologies.

The 5th Conference aims to presents the latest developments in lasers and laser technologies for the feasibility of laser ignition in practical combustion systems. The latest developments in non-laser ignition systems and studies that enhance our understanding of the ignition process will also be presented. 

Sponsorship for the meeting is from the European Union, the Micro Solid-State Photonics Group of the Laser Society of Japan and in cooperation with The Optical Society and several academic societies and associations.

Combining regenerative and classical fossil energy sources is a major issue to be addressed in order to find solutions to the challenges of modern societies with respect to technology advances and low carbon footprint at the same time. Fossil energy sources will remain on the tableau due to their energy density and the mobility of combustion engines for cars, power trains, aviation, space and energy cogeneration, but only an efficient and low fuel usage will allow those to contribute to a low carbon footprint mix of energy. Laser-based ignition is believed to be a major contributor to efficient fossil fuel usage and thus a lower carbon footprint of mankind due to the variability and shape-ability of laser pulses that replace the electric spark to ignite the gas-fuel mixture. But a number of technological challenges need to be proved before laser spark plugs can realistically be adopted. 

1. Developments in laser & laser technologies - applications in laser ignition
  • Micro solid-state photonics: advanced laser crystals, ceramics and micro-domain controlled materials;
  • Giant micro-photonics: mega-watt class giant pulse generation, laser damages phenomena;
  • High power devices: high power VCSELs, DFB and VBG based diodes, fiber and fiber lasers etc.
  • Integration approaches for harsh environmental suitable laser systems.
2. Advanced ignition systems for transportation applications

3. Laser ignition systems for stationary natural gas engines

4. Laser ignition in aerospace applications

5. Measurement techniques for induced plasmas, ignition & combustion processes

6. Round table discussions - standardization, legislative, political and social-ethical challenges for laser ignition

Pollutant Emissions Reduction of Internal Combustion Engines by using Alternative Fuels and Enhanced Ignition Systems
Abstract: The researches performed for improvement of internal combustion engines performance using alternative fuels and enhanced ignition systems will be discussed. These approaches address the concerns about availability of petroleum derived fuels and pollutant emissions level.

Radu Chiriac graduated in 1982 the Faculty of Mechanical Engineering from University “Politehnica” of Bucharest. He obtained his PhD Diploma in 1995, from the same university, in the field of thermal equipment-internal combustion engines. Currently, Radu Chiriac is full professor at Department of Thermodynamics, Heat Engines Thermal and Refrigerating Equipments from “Politehnica” University. Since 2010 he is associated member of Chaire de Turbomachines et Moteurs from Conservatoire National des Arts et Métiers, Paris. He is member of The Society of Automotive Engineers, USA. His research activities are related to alternative fuels for internal combustion engines, combustion investigation, simulations of the internal combustion engines processes, heat transfer and fluid dynamics.

Nonequilibrium Plasma-Assisted Combustion: Advanced Spectroscopic Methods for Fundamental Studies

Abstract: Non-equilibrium plasmas have strong potential to enhance performance of combustion systems due to generation of large numbers of reactive species. Kinetic and dynamic fundamental studies using advanced spectroscopic diagnostics are presented.

Gabi Daniel Stancu obtained his PhD in plasma spectroscopy at University of Greifswald, Germany in 2004. He was then a research fellow in a couple of academic institutions, and since 2010 he is an associate professor at Ecole Centrale Paris, France, today CentraleSupélec. His current activity is devoted to development of advanced spectroscopic diagnostics for non-equilibrium plasmas and to understanding of fundamental kinetic and dynamic mechanisms in reactive plasmas, in particular in plasma-assisted combustion.

The Evolution of Laser Ignition over Four Decades

Abstract: Laser spark ignition of reactive gases was first attempted in 1969; one decade later first engine tests were achieved. Several concepts for an ignition scheme including fiber transportation of ns pulses were pursued successfully. A number of different prototypes, mostly Nd:YAG lasers, transversally or longitudinally, directly or fiber-transmission pumped were developed. Studies have shown that the problem of window failing can be avoided. The temperature management for the solid-state as well as the diode lasers still represent major problems in laser ignition of car engines to date.

Ernst Wintner received his PhD in Physics in 1976 from University of Vienna with a thesis on “Electron Microscopy of Partial Dislocation Structures in CuAl Alloys”. He changed to the field of Photonics when joining TU Vienna in 1976. In 1992 he was promoted titular full professor of Applied Laser Technology; since Oct. 2015 he is retired. His scientific work comprises nonlinear optics, fiber optic sensors, solid-state lasers, ultra-short pulse generation, and applications in materials processing and dental medicine. Together with GE Jenbacher, Austria, he founded the Laser Ignition Research Group in 1998. His external activities comprise visiting scientist at M.I.T. 1982 - 1984 and at Friedrich-Schiller-University, Jena in 1986, Visiting Professor to Institute of Laser Engineering, Osaka University, 2000-2001, and Indian Institute of Technology Kanpur in 2013.  He is (co)author of more than 250 scientific publications including 7 book chapters and member of several professional organizations.
