description

Darbā tiek izpētīti teorētiskie optiskā magnetometra darbības principi, klasiskais optiskā magnetometra darbības modelis. Darba gaitā padziļināti apgūti teorētiskie principi, kas ir pamatā magnetometra, kurā tiek veikta sārmu metālu pamatstāvokļa optiskā pumpēšana, darbībai. Tiek veikta ūdeņraža un sārmu metālu atomu uzbūves modeļu izpēte, īpašu uzmanību pievēršot enerģijas līmeņu uzvedībai magnētiskā lauka klātbūtnē- normālajam un anomālajam Zēmana efektam- kā arī atomu sīkstruktūrām un superīkstruktūrām. Darba gaitā tiek veikta optiskā magnetometra signāla modelēšana sistēmai, kurā tiek izmantota Rb D1 līnijas ierosme, reģistrējot cirkulāri polarizētas gaismas absorbcijas signālu atkarībā no ārēja, stacionāra un ārēja, ar radiofrekvenci oscilējoša magnētiskā lauka. Modelēšanu veic, pielietojot blīvuma matricu formālismu. Modelējot tiek iegūts absorbcijas signāls dažādām eksperimentālo parametru vērtībām. Tiek veikta kvalitatīva modelēto un eksperimentāli iegūto signālu salīdzināšana.
