The German Electron Synchrotron Research Center (DESY) in Hamburg has made a groundbreaking advancement with the development of an ultra-powerful laser, bringing scientists significantly closer to observing chemical reactions in real time. This innovation marks a major step forward in understanding molecular processes at an atomic level. According to a recent report from German media, a team of international researchers at DESY has successfully built a free-electron laser. The facility includes a 250-meter-long acceleration system and a large laboratory measuring 30 by 50 meters. The laser works by generating a compact bundle of 10 billion electrons within a tiny 0.1 x 0.1 mm area. These electrons are then accelerated to nearly the speed of light and passed through a long magnetic structure. As they move through this setup, the electrons are guided along a wave-like path, causing them to emit light. This light ultimately synchronizes with the electrons, producing a powerful laser beam. Professor John Schneider, the project’s lead researcher, emphasized that this short-wavelength laser opens up new possibilities for exploring the nanoscale world. It will enable scientists to conduct experiments across various fields, including physics, chemistry, materials science, geology, and life sciences. The laser is expected to be a game-changer in research, offering unprecedented insights into molecular interactions. Notably, Germany is set to become the first country in the world to possess such a cutting-edge laser by 2008. This achievement underscores the nation's leadership in advanced scientific research. This new laser is just one component of a broader initiative aimed at capturing real-time chemical reactions and the movements of biomolecules. To achieve this, particles will be accelerated through a 3.3-kilometer underground tunnel, where they will emit X-rays at near-light speeds. These X-rays will serve as a critical tool for obtaining detailed structural and dynamic information about atomic systems. The tunnel is currently under construction near Hamburg, signaling the next phase of this ambitious scientific endeavor.
