V obeh primerih imamo opravka s kratkimi, femtosekundnimi sunki svetlobe, pri virih FEL pa je gostota toka na tarči lahko tako visoka, da lahko opazujemo nelinearne pojave tudi pri kratkih valovnih dolžinah svetlobe. V predavanju bomo opisalo dve aplikaciji novih virov svetlobe v atomski fiziki: pri prvi smo z virom HHG v Laboratoriju za kvantno optiko UNG opazovali Autler-Townesov razcep stanja z vzbuditveno energijo 60.2 eV, pri drugi pa smo z virom FEL FERMI opazovali interferenco dvofotonskih poti iz osnovnega stanja atoma v stanje z vzbuditveno energijo 57.8 eV.<o:p></o:p></span></span></span></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk41995074'><span style='mso-bookmark:_Hlk41470923'><span style='mso-bookmark:_Hlk20313133'><span style='mso-bookmark:_Hlk50455726'>Predavanje bo v slovnščini.<o:p></o:p></span></span></span></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span style='mso-bookmark:_Hlk41995074'><span style='mso-bookmark:_Hlk41470923'><span style='mso-bookmark:_Hlk20313133'><span style='mso-bookmark:_Hlk50455726'><strong><span style='font-family:"Calibri",sans-serif'>Lepo vabljeni!</span></strong></span></span></span></span><span style='mso-bookmark:_Hlk50455726'><strong><span style='font-family:"Calibri",sans-serif'><o:p></o:p></span></strong></span></p><span style='mso-bookmark:_Hlk50455726'></span><p class=MsoNormal><o:p> </o:p></p></div></body></html>
