Abstract : We present what we believe to be the first true three-level laser based on a Nd-doped crystal. From the 4F3/2-4I9/2 laser transition, the lower laser level being the ground state, emission at 879 nm in NdGdVO4 has been obtained with diode pumping. Up to 0.8W of power has been achieved in cw operation and 24_J per pulse _35 ns_ in the Q-switched regime. Intracavity second-harmonic generation in the pulsed regime is also demonstrated with 178mW of average output power at 439.5 nm, corresponding to an energy of 17_J per pulse
