We have demonstrated passively Q-switched mode-locking in a laser-diode-pumped Nd : GdVO4 laser with an intracavity Cr4+ : YAG saturable absorber. At a pump power of 19.4 W, the Q-switched mode-locked laser produced an average output power of 3.22 W, and the repetition rates of the Q-switched envelope and the mode-locked laser pulse were 227 kHz and 144 MHz, respectively. The duration of the mode-locked pulse was within the sub-nanosecond range.
