Abstract:
Natural radiative lifetimes of eight levels in Tm I ( 4f 135d6p and 4f 125d6s 2 configurations), two levels in Tm II ( 4f 125d6s configuration) and three levels in Tm III (4f 125d configuration) have been measured by using time-resolved laser spectroscopy. Free thulium atoms, as well as singly and doubly ionized ions, were obtained in a laser-induced thulium plasma and the investigated states were selectively populated by a single-step excitation process with a tunable narrow-band laser pulse.
