Zusammenfassung:	The parametric studies of a laser-diode (LD)-pumped, acousto-optic (AO)-mode-locked and Q-switched Nd:YAG laser were carried out. Adequate compensation for the thermal lensing in the longitudinally pumped laser rod was provided by analyzing the spot size in the astigmatically compensated cavity. The width of the mode-locked pulse with 0.5 nJ output energy per pulse was elongated to 910 ps by means of an intracavity etalon. Good stabilities of the output energy (±3%) and the peak power (±5%) were obtained, which are comparable to those of the flash-lamp-pumped mode-locked Q-switched lasers.
