By applying low‐dose oxygen ion implantation, active planar waveguides in Nd 3+ doped near‐stoichiometric lithium niobate laser crystals have been, for the first time to our knowledge, successfully produced. The waveguide exhibits good transmission properties with relatively low propagation loss of ∼2 dB/cm. The confocal micro‐luminescence investigations indicate that the emission properties of Nd 3+ ions in the waveguide are well preserved with respect to the bulk, thus showing promising potentials for efficient waveguide laser action operating at the Nd 3+ near‐infrared bands.
