While “going green” is a familiar concept, the materials and processes needed to make real change are constantly evolving to better protect our environment. The automotive industry continues to embrace green technologies to meet environmentally conscious consumer demands and to position themselves over the competition.
ELI Beamlines, Lawrence Livermore National Laboratory (LLNL), and Leonardo Electronics US Inc. have teamed up to advance high-power laser capabilities in their pursuit of a petawatt laser. This global collaboration has already demonstrated significant performance improvements for laser technologies, specifically for the LLNL-developed High-Repetition-Rate Advanced Petawatt Laser System (L3-HAPLS), with implications for a range of promising applications.
At the recent DEPS Systems Symposium, Leonardo’s John Goings presented key advancements in directed energy pump sources. His presentation, titled “The Road to Power Scaling and Industrialization of Directed Energy Pump Sources,” reviewed the role of semiconductor laser diodes, the pumping source, in directed energy laser systems.
Physicists have been conducting extensive research for decades to explore the feasibility of fusion-based energy production, looking to tap what could be a trillion-dollar market with the hope of achieving the ultimate, clean, nearly inexhaustible source of energy.
ELI Beamlines, a part of the Extreme Light Infrastructure (ELI) pan-European project of scientific excellence in Europe, aims to operate some of the world's most intense laser systems. Lawrence Livermore National Lab (LLNL) was awarded the contract for the L3 laser system from ELI Beamlines, and both teams had come together on development of a high-average-power, high-energy system—a petawatt laser operating at 10 Hz.
In the last several years, there has been a growing demand for technology to support smart city applications. The idea being that a city empowered by data allows for greater efficiency in almost any aspect. Benefits range from ensuring faster, more accurate response times for first responders to analyzing traffic patterns for better infrastructure design. Big data, artificial intelligence, and reliable sensing technology are all essential for this to be successful.
Thermal imaging technology has been in development since the early 1930’s and has seen widespread use since the beginning of World War II. Leonardo’s thermal imaging technology has continued to evolve since. In 2020, Leonardo offers a wide range of thermal imaging technologies for various applications across industries and the globe. Reducing cost and improving usability have been the major focuses among industry leaders in broadening capabilities.
Demand for directed energy weapons is growing rapidly, projected at a CAGR of 23.26% through 2025, to meet the Department of Defense’s need for accuracy and precision of non-lethal weapons to combat emerging threats such as UAVs. As threats broaden, so do needed platforms: man-portable, ground or naval-based air defense against aerial targets and long-range, short-range, and medium-range strategic missions.
Beginning on Tuesday, April 28, Leonardo Electronics US will host a three-day virtual conference to discuss recent advancements in customizable laser diode sources and laser system product lines. Complete with technical webinars, question and answer sessions and 1:1 private briefings, registrants have the opportunity to discuss topics in rapidly changing industries such as directed energy, automotive lidar and security.
We have previously written about many of the technical aspects of laser diode design, such as cooling systems, electrical power sources, and diode structure. It is critical to remember that automotive lidar systems operate principally outdoors, meaning an important consideration is the surrounding environment. For automotive lidar, there are four main factors to consider when selecting and designing the laser diode that lies at the heart of the lidar system.
