Spontaneous emission inhibition of erbium ions at 1.5 µm wavelength is obtained by tailoring direct femtosecond‐laser‐written 3D photonic structures inside lithium niobate laser crystals. This technique allows for engineering of the structure symmetry and filling fraction by spatially inscribing laser‐induced amorphous voxels inside the crystalline sample.
