The spectroscopy of a cloud of Calcium atoms for the experiment of laser cooling
Grim, Jakub ; Pham, Minh Tuan (referee) ; Číp, Ondřej (advisor)
The thesis is focused on the research on methods of generating calcium atoms into ion traps. To be specific, it is a pulse laser ablation method and generating by the calcium heat oven heated by electric current, which is currently being used. Part of the thesis is the design of experimental apparatus for the generation of calcium atoms including vacuum and optical assembly and subsequent experimental assembly itself according to design. At the end, there is an experiment, where is used electric current for heating the oven, ablation laser for ablation of calcium atoms and fluorescence spectroscopy for detection of generated neutral calcium atoms.

Laser ablation of calcium atoms for laser cooling experiment
Grim, Jakub ; Pham, Minh Tuan ; Číp, Ondřej
Our work describes two most common methods of generating neutral atoms needed for experiments with trapped and cooled ions. The easiest but not most effective way of the neutral atoms generating is to use a heated oven. A better method allowing a fine control of generating atoms is to use a pulsed laser ablation. A vacuum chamber with Ca atoms source and necessary optics was assembled. Detection of generated particles was achieved by laser-induced fluorescence and sensitive camera. The paper consists of measurement of both method of generating the atoms.
