Pulsed laser operation in the afterglow of a positive column He-Kr discharge on the 469.4 nm (6s{sup 4}P{sub 5/2} {yields} 5p{sup 4}P{sub 5/2}) transition of Kr(II) was observed for the first time by Dana and Laure`s. It appears that the upper level of Kr(II) laser line is populated by the second kind collisions between He 2{sup 3}S metastable atoms and ground state Kr ions. CW oscillations on Kr(II) transitions have been obtained in a hollow cathode discharge. In this work, we have estimated the excitation mechanism for the upper state of 469.4 nm laser line from the measurements of the decay of endlight intensity in the hollow cathode He-Kr discharge.
