Kontinuirano opazovanje in merjenje interferenčne slike neodvisnih laserjev : disertacija
Verovnik, Ivo
Opisan je nov način opazovanja in merjenja interferenčne slike, ki jo dobimo sestavljanjem svetlobe dveh He-Ne laserjev. Napravo, ki jo imenujemo fluktuacijski interferometer, lahko sestavimo v ...šolskem laboratoriju. Osnovna zamisel temelji na Youngovem interferenčnem poskusu z dvojno režo. Če eno režo osvetlimo s svetlobo enega od laserjev in drugo režo s svetlobo drugega neodvisnega laserja, se interferenčna slika na zaslonu translacijsko premika. V najpreprostejši verziji eksperimenta se zaradi različnega spreminjanja temperature laserskih resonatorjev v določenih časovnih presledkih pojavijo nizkofrekvenčne fluktuacije sestavljenega signala dveh svetlobnih detektorjev. S preprosto povratno zanko, ki temelji na ohlajanju enega od laserjev z ventilatorjem, priklenemo frekvenco enega od laserjev na drugega, kar nam omogoča kontinuirano detekcijo signala fluktuacijskega interferometra
