Abstract
U ovom diplomskom radu proučavani su mehanizmi Dopplerovog i sub-Dopplerovog hlađenja atoma rubidija zarobljenih u magneto-optičkoj stupici (MOT). Razvijena je i implementirana tehnika vremena proleta koja zahtjeva vrlo preciznu i brzu kontrolu lasera i magnetskog polja. Promatrana je ovisnost temperature o intenzitetu lasera za hlađenje i o pomaku frekvencije lasera za hlađenje. Izmjerene vrijednosti pokazale su ponašanje predviđeno teorijskim modelom sub-Dopplerovog hlađenja. Najniža izmjerena temperatura je T = 21.95 μK. U drugom dijelu rada mjeren je pomak centra mase zbog djelovanja sile zračenja lasera za guranje u ovisnosti o frekvenciji tog lasera. Ispitivana je nova metoda za mjerenje AC Starkovog pomaka zbog utjecaja lasera (engl. light shift). Zbog osjetljivosti o velikom broju faktora kada se radi s tako visokim rezolucijama i niskim temperaturama, pokazalo se da predložena metoda za mjerenje light shifta zahtjeva dodatno usavršavanje eksperimentalnog postava.
Abstract (english)
In this thesis Doppler and sub-Doppler cooling mechanisms were studied. Time of flight technique that requires very fast and precise laser and magnetic field control was developed and implemented. Temperature dependence on the intensity and frequency of the cooling laser is observed. The measured values showed a good agreement with the theoretical model for sub-Doppler cooling. The lowest temperature we measured was T = 21.95μK. Center of mass movement due to the radiation pressure force from the pushing laser was measured in dependence of the laser frequency. A new method for measuring light shift was tested. It was concluded that more work on the experimental setup is needed, due to the very big sensitivity on many factors when dealing with such low temperatures and high resolution.
