Abstract

We report a sub-250-nm, optically pumped, deep-ultraviolet laser using an Al_xGa_1-xN-based multi-quantum-well structure grown on a bulk Al-polar c-plane AlN substrate. TE-polarization-dominant lasing action was observed at room temperature with a threshold pumping power density of 250 kW/cm². After employing high-reflectivity SiO₂/HfO ₂ dielectric mirrors on both facets, the threshold pumping power density was further reduced to 180 kW/cm². The internal loss and threshold modal gain can be calculated as 2 cm^-1 and 10.9 cm ^-1, respectively.
