The mode locking of a cw Nd:YAG laser by translation one the cavity mirrors is reported. mode-locking effect greatly enhanced when an intracavity nonlinear KTP crystal used. Stable pulse trains with 60-ps average width are obtained. Theoretical analysis shows that combined linear phase shift imposed moving mirror and in Kerr medium gives rise to saturable-absorber-like behavior homogeneously broadened laser. theory agrees well experimental results as obtained Ti:sapphire
