High-frequency, advanced PicoWatt lasers (HAPLS) developed by Lawrence Livermore National Laboratory (LLNL) for the European Extreme Light Infrastructure (ELI) beam project created diode-pumped wafer watts (10 of 15 square watts Laser system world record. Lawrence Livermore National Laboratory said the breakthrough means the laser system can already be used for the delivery and integration of the EU's extreme light infrastructure beam project in Prague, Czech Republic. Lawrence Livermore National Laboratory's HAPLS team "The main beam" One of the features of the HAPLS system described by ELI stakeholders is the "L3" beam. The beam is the "main" beam of the new device, featuring ultra-short optical pulses of high energy and high repetition rate that provide scientists with the ability to successfully conduct cutting-edge experiments. LLNL means that a HAPLS system at a frequency of 3.3 Hz can transmit 16 joules per 28 femtosecond laser pulse - that is, about 0.5 megawatts of energy per pulse. LLNL director Bill Goldstein said in a report by a U.S. equipment giant that includes a National Ignition Facility (NIF) that "Twenty years ago, LLNL led the development of the world's first NOVA solid-state lasers for wattage lasers, which is the peak A huge breakthrough in power, HAPLS is now leading a new era in wattage lasers and is getting unprecedented performance requirements. " The HAPLS team announced at the SPIE West Optoelectronics Exhibition in collaboration with the Austrian Femtolasers company the development of a HAPLS system for the development of pulsed pulsed lasers with frequencies up to 10 Hz and only three years later the team received the latest technological achievements. Femtolasers was subsequently acquired by Spectra-Physics, a laser and is now a subsidiary of MKS Instruments. Since the HAPLS system was shipped to Prague in 2016, the plan to vibrate the floor on the way to the Czech base has been postponed and the progress has been postponed. Relevant personnel at the recent Photoelectric Show in the western United States responded that the L3 beam system is expected to be up and running for the first time in early 2018. In addition, LLNL added: "In just three years, HAPLS has gone from concept to fully integrated or even become a breakthrough record of the entire product process.HAPLS using the United States Department of Energy fusion laser research and development of innovative technologies, represents a new A generation of diode-pumped, high-energy, high-peak-power laser systems with application support features. " Important turning point Constantin Haefner, project director for advanced photonic technology at LLNL, presented the details of the HAPLS development at this 2017 Western America Optoelectronics show: "The HAPLS system's high-frequency feature is a key turning point in the field and the HAPLS system was the first to truly deliver The application sets up a repetition rate watt-hour laser. " The key component that determines its performance is a high-power laser diode array provided by diode manufacturer Lasertel. Roman Hvezda, head of the ELI beam project, added that HAPLS has "done everything" for its research and development. "By design, no one else was able to deliver the system with a limited budget for such a short period of time, and we were greatly benefited by our partnership with the fully-equipped Livermore Laboratory, which also provided our future Continue to lay the foundation for cooperation. " Throughout the development of the laser system, scientists and engineers at the LLNL and ELI beam projects have been closely aligned. Haefner said: "One of the real hard-won successes was the fact that commissioning parties were fully involved in the commissioning and operation of the laser system from the very beginning, which provided conditions for internship training and the introduction of expertise that effectively ensured the laser integration process The operational success. " The HAPLS system is currently being transferred to the ELI beam project site and will be integrated into the laser transmission and control system to produce laser pulses in excess of 1 beatwave peak power at 10Hz repetition rate.
