Researchers develop new electrically pumped edge-emitting laser chip with unprecedented performance

In a new study published in Light: Science & Applications , a team of scientists led by Asst. Prof. Abdullah Demir from UNAM-Institute of Materials Science and Nanotechnology, Bilkent University, has successfully developed a novel electrically pumped edge-emitting laser chip with unprecedented performance. This large-area quasi PT-symmetric laser has single-mode output power levels of 400 mW while maintaining beam quality comparable to narrow waveguide laser devices, and operates at room temperature without cooling.
