YAlO/sub 3/:Er laser crystals with medium dopant concentration can emit on different transitions of the /sup 4/I/sub 11/2/..-->../sup 4/I/sub 13/2/ manifolds within a laser pulse. In a 20-at. % doped a rod the three most prominent laser lines oscillate at wavelengths of lambda/sub 1/ = 2.73 ..mu..m, lambda/sub 2/ = 2.79 ..mu..m, and lambda/sub 3/ = 2.92 ..mu..m. The temporal sequence of lambda/sub 1/, lambda/sub 2/, and lambda/sub 3/ within a train of relaxation oscillations has been measured and is analyzed on the basis of inversion, linewidth of transitions, and ion-ion interaction in the /sup 4/I/sub 13/2/ state.
