The pulse shaping dynamics of a diode-pumped laser oscillator with cavity dumping operating in the solitary regime is studied experimentally and numerically. The stability of the laser system is investigated in dependence on the relevant laser parameters. With a stroboscopic detection technique the intracavity temporal and spectral pulse profiles are measured between two dumping events. The results are compared to the numerical analysis of the system. Due to the strong periodic disturbance of the solitary pulse imposed by the dumping process a second set of Kelly-side bands can be identified.
