Short­est, fastest light pulse ever de­vel­oped

The Hitavada - - WORLD -

SCI­EN­TISTS have gen­er­ated the fastest and short­est light pulse, that will help cap­ture sharper-than-ever im­ages of fast-mov­ing elec­trons and en­able ad­vance­ments in smart­phone and com­puter tech­nolo­gies.

The 53-at­tosec­ond pulse, achieved by re­searchers at the Univer­sity of Cen­tral Flor­ida in the US, beats the team’s pre­vi­ous record of a 67-at­tosec­ond ex­treme ul­tra­vi­o­let light pulse set in 2012. At­tosec­ond light pulses al­low sci­en­tists to cap­ture im­ages of fast-mov­ing elec­trons in atoms and mol­e­cules with un­prece­dented sharp­ness, en­abling ad­vance­ments in so­lar panel tech­nol­ogy, logic and mem­ory chips for mo­bile phones and com­put­ers, and in the mil­i­tary in terms of in­creas­ing the speed of elec­tron­ics and sen­sors, as well as threat iden­ti­fi­ca­tion.

“This is the short­est laser pulse ever pro­duced. It opens new doors in spec­troscopy, al­low­ing the iden­ti­fi­ca­tion of per­ni­cious sub­stances and ex­plo­sive residue,” said Rich Ham­mond from the US Army Re­search Of­fice (ARO).
