We report theoretically and experimentally open-Dirac cavities that exploit symmetry-dependent scaling of losses in cavities with a linear dispersion. We experimentally demonstrate that single-mode lasing from surface emitting lasers operating around the open-Dirac singularity is maintained even when the cavity is scaled up to arbitrary sizes. Our work constitutes the first scale-invariant surface emitting laser.
