An active-passive mode-locked Nd:YAG oscillator provides greatly improved shot-to-shot reproducibility compared with passive mode-locking. Effects of modulator drive power, laser cavity length, and intracavity etalons on the pulse width and stability are given. Using two-photon-fluorescence techniques the pulse width was 35.9 ± 1.7 psec and the corresponding pulse energy was 166 ± 6 µJ.
