Generation of watt-level optical quasiparticles with a dual output coupling configuration in a diode-pumped Nd:YVO <sub>4</sub> laser

We demonstrate experimentally the generation of 1064 nm watt-level optical skyrmions and bimerons with first order Néel, Bloch, and anti polarization textures based on a continuous-wave Nd:YVO<sub>4</sub> laser with a dual output coupler cavity configuration. The estimated skyrmion number of these quasiparticles is > 0.94.
