The generation of multicolor (523, 605, 637, and 719 nm) optical quasiparticles (bimerons and skyrmions with topologically protected polarization textures) from a diode‐pumped Pr3+‐doped fluoro‐aluminate glass (Pr3+: WPFG) fiber simply with intra‐cavity plano‐convex lens and wedge‐plate and without any wavefront control elements, such as a spatial light modulator is demonstrated. This robust and cost‐saving system efficiently produces Bloch‐, Néel‐, and anti‐quasiparticles with high mode purity. In particular, the green optical quasiparticles will have the potential to explore many applications in materials science and biotechnologies.
