U \u010dasopisu Nature Photonics objavljen je rad grupe nau\u010dnika kojim je opisan prvi u istoriji dokazano uspje\u0161an slu\u010daj skretanja munje, tj. pra\u017enjenja atmosferskog elektri\u010dnog naboja, uz pomo\u0107 lasera. Nau\u010dnici, koji su na ovome radili, na vrh \u0161vajcarske planine Santis, na visini od 2.500 metara nadmorske visine, postavili su sna\u017ean laserski sklop, uz telekomunikacioni toranj. O\u010dekivano, taj toranj je \u010desta meta udara munje, pa je i dobro mjesto za prou\u010davanje u\u010dinkovitosti lasera u njegovoj odbrani.<\/p>\n

Eksperiment je trajao od jula do septembra 2021. godine, a u svrhe vo\u0111enja putanje munje kori\u0161\u0107en je pikosekundni laser, onaj koji je u stanju da nabijeni svjetlosni puls izbacuje do hiljadu puta u sekundi. Taj je laser uklju\u010divan isklju\u010divo tokom grmljavine, a zabilje\u017eio je oko \u0161est sati eksperimentalnog rada.<\/p>\n

Za vrijeme eksperimenta telekomunikacioni toranj bio je pogo\u0111en munjom najmanje 16 puta, od \u010dega \u010detiri puta za vrijeme rada lasera, prenosi Bug.hr.<\/p>\n
