EPJ ST Highlight - A new era of research into laser-matter interactions

A new collection of papers provides new experimental and theoretical perspectives on the interaction between matter and intense laser beams

Studies of laser-matter interactions are an important and rapidly growing area of physics. This special issue of EPJ ST, edited by Sivarama Krishnan at the Indian Institute of Technology Madras and Marcel Mudrich at Aarhus University, Denmark, contains a set of 21 articles in this field, encompassing a broad range of experimental and theoretical approaches. The collection provides researchers with useful insights into this burgeoning area of science, and the exciting applications it may soon lead to.

In 2018, physicists Gérard Mourou and Donna Strickland shared a Nobel prize for their success in amplifying ultra-short laser pulses, without destroying the material required for amplification. Their achievement has now inspired a new era of studies into laser-matter interactions, in which intense, ultra-short light pulses at optical and infrared wavelengths play a central role. When the strengths of these light fields approach those of the extreme electric fields found within atoms, nanoparticles and condensed crystal lattices, they can induce highly nonlinear properties: meaning matter will respond disproportionately to any changes in the light inducing them.

When ionised in this way, materials can transform into plasmas with drastically altered optical properties. For physicists, an overarching challenge of future research in this area will be to deepen their understanding of these laser-induced plasmas. In addition, researchers are developing new ways to use them for novel applications: including biomedical imaging, laser-driven particle acceleration, and techniques for precisely etching or depositing microscopic patterns onto thin films.

Another key pillar of this work is the emission by matter of high-frequency harmonics contained in laser beams – enabling the study of physical dynamics over timescales of just billionths of a nanosecond. In doing this, physicists will need to use a combination of creative experimental methods and advanced new theoretical approaches. This collection of articles now draws together the efforts of both leading and upcoming researchers from institutions around the world, each studying a wide range of areas within this rich field of research.

All articles are available here and are freely accessible until 4 April 2022.

This was our first experience of publishing with EPJ Web of Conferences. We contacted the publisher in the middle of September, just one month prior to the Conference, but everything went through smoothly. We have had published MNPS Proceedings with different publishers in the past, and would like to tell that the EPJ Web of Conferences team was probably the best, very quick, helpful and interactive. Typically, we were getting responses from EPJ Web of Conferences team within less than an hour and have had help at every production stage.
We are very thankful to Solange Guenot, Web of Conferences Publishing Editor, and Isabelle Houlbert, Web of Conferences Production Editor, for their support. These ladies are top-level professionals, who made a great contribution to the success of this issue. We are fully satisfied with the publication of the Conference Proceedings and are looking forward to further cooperation. The publication was very fast, easy and of high quality. My colleagues and I strongly recommend EPJ Web of Conferences to anyone, who is interested in quick high-quality publication of conference proceedings.
