We present, for what we believe is the first time, results of continuous-wave diode-pumping of a Nd:YVO 4 laser with an adaptive gain-grating resonator. The system is shown to produce more than a 7-W output in a TEM>00 single longitudinal mode with a laser beam propagation parameter M2 of <1.3 and <1.1 in the x and y axes, respectively. We demonstrate the self-adaptive abilities of the resonator by spatial correction of an intracavity aberrator for both injected and self-starting versions of the cavity.
