Catastrophes in Nonlinear Compton Scattering - catastrophes that are actually helpful
Imagine a wine glass standing on a table lit by a light bulb above it. When we look on the table at the image of the glass, we will see bright spots and lines known as caustics (see Figure 1). They appear because we map light coming from the bulb on the table surface using a complex three-dimensional object. It is quite reasonable that different light rays coming from the bulb and going through the glass can be projected to the same point on the table, and this is exactly what leads to the appearance of the bright spots. The mathematical theory that describes the singularities of such projections is called the catastrophe theory. Researchers from Helmholtz Institute Jena have applied this beautiful theory to the process of scattering of high-intensity laser pulses from energetic electrons and found a new way to substantially increase the photon yield of X- and gamma-ray sources.
Indeed, mathematical procedure of finding the radiation properties of the electron moving in the laser field is similar to the projection of the light coming from the bulb on the table through the wine glass. Instead of the light rays from the bulb, now one uses locally emitted photon wave vectors and projects them on the overall detected energy-angular spectrum (see Figure 2).
Shaping the local emission properties by the laser pulse envelope or chirping can lead to the appearance of the well-defined bright spots in the scattered radiation spectrum, just like different shapes of wine glasses produce different caustics on the table. This theoretical finding can lead to the significant improvement and size reduction of X- and gamma-ray photon sources based on nonlinear Compton scattering for usage in nuclear physics, material science, medicine, biology etc.”

Start-up Class 5 Photonics wins PRISM AWARD
Class 5 Photonics, a spin-off from Helmholtz-Institut Jena and from Deutsches Elektronen-Synchrotron DESY specialized in high-performance laser technology, is the proud winner of the PRISM AWARDS 2018 in the category lasers. SuperNova OPCPA is the Class 5 Photonics flagship product, which took the trophy home. The SuperNova OPCPA enables researchers to perform experiments ten times faster than with conventional lasers.
“We are delighted to win this prestigious award and being recognized as the premier laser technology partner for the most advanced R&D labs and institutions worldwide,” said Class 5 Photonics CEO and co-founder Robert Riedel. “With our products we aim to enable cutting-edge research to gain new insights in processes, building blocks and interactions in physics, chemistry and bio sciences.”
The PRISM AWARDS are the premier worldwide event in the photonics industry and awarded annually during the SPIE Photonics West conference and tradeshow in San Francisco. More than 150 applicants entered the competition in ten categories this year. With its high-performance laser SuperNova OPCPA Class 5 Photonics convinced the jury.
The spin-off company was founded in 2014 in Hamburg. The scientists from Helmholtz Institute Jena and DESY are developing high power lasers with pulses in the femtosecond range. One femtosecond is a quadrillionth of a second. Shorter laser pulses allow more precise working of materials, for instance. Also, such short laser pulses open up new innovative applications like 3D nanostructuring. For science, the technology is of great importance.
PhD Position available
We would like to announce the opening of a PhD position in the Theoretical Atomic Physics group of the Helmholtz Institute Jena (advisors: A. V. Volotka and S. Fritzsche) on quantum electrodynamics of highly charged ions.
A detailed description of the PhD project can be found at www.atomic-theory.uni-jena.de

2nd International Conference on Nuclear Photonics (Nuclear Photonics 2018), Brasov Romania
The focus of the conference will be on: fundamental nuclear science and spectrometry, laser-plasma nuclear physics, high-intensity laser-plasma interaction, nuclear medicine including radiography and radiotherapy, industrial non-destructive material imaging and evaluation, isotope-specific nuclear materials detection and management, photon-based hadron beams and applications, photon-based production of rare isotopes, photon-enabled pulsed neutron generation and science, photon-enabled pulsed positron generation and science, nuclear astrophysics and cosmology, gamma-ray science above the giant dipole resonance, strong field QED. The conference program will consist of invited lectures, contributed presentations and posters. The posters will be featured in the exhibition for the whole duration of the conference. We strongly encourage young researchers and students to participate with posters. Their posters will participate to the Best Posters awards competition.
The contributed presentations and the posters will be selected by the Program Committee based on abstract submission. The deadline for abstract submission was extended to February 28th 2018. Detailed information on the conference is available on the webpage: http://nuclearphotonics2018.eli-np.ro
