| Research Abstract |
Five External Cavity Diode Laser systems were constructed in order to excite neutral atoms to photoionize and ions to excite highly excited states。 These laser systems enabled ones to make isotopically selective excitations and photoionization of atoms。 Fluorescence from trapped ions was observed with a CCD camera from z-axis direction。 A highly excited state of the trapped ions was confirmed with the laser excitation。 Dynamics of individual ions in Coulomb crystal were successfully observed。
