Phys.org  January 16, 2023 An international team of researchers (France, Switzerland, Germany, USA – New Mexico Institute of Mining and Technology, Sweden) conducted the first field-result that experimentally demonstrated lightning guided by lasers. They conducted an experimental campaign on the Säntis mountain in north-eastern Switzerland during the summer of 2021 with a high-repetition-rate terawatt laser. The guiding of an upward negative lightning leader over a distance of 50 m was recorded by two separate high-speed cameras. It was corroborated in three other instances by very-high-frequency interferometric measurements, and the number of X-ray bursts detected during guided lightning events greatly increased.
