Nonlinear two-photon pumped vortex lasing based on quasi-bound states in the continuum from perovskite metasurface
The experimental observation of nonlinear two-photon pumped vortex lasing from perovskite metasurfaces is demonstrated. The vortex lasing beam is based on symmetry-protected quasi-bound states in the continuum (QBICs). The topological charge is estimated to be +1 according to the simulation result....
