Laser ablation of calcium and aluminium atoms as a particle source for ion trap
Grim, Jakub ; Pekař, Zdeněk ; Pham, Minh Tuan ; Číp, Ondřej
Laser ablation is an effective method for generating particles from a variety of materials, including those with high evaporation temperatures such as aluminum. The use of high-energy laser pulses enables controlled evaporation of the material and the creation of an ablation crater. Successful results have been obtained in a pilot setup for the generation of neutral calcium and aluminium atoms by laser ablation. The method is being compared with thermal resistance oven in order to optimize the prosec generation of these particles. Subsequent spectroscopic measurements on the generated atoms are performed to optimize the absorption and emission of photons for subsequent ionization in the ion trap. A study of the transitions of neutral Ca and Al atoms shows that laser ablation provides a more efficient generation of atoms with the possibility of greater control over the process.
