Rare-earth-based lasing in multiple bands simultaneously - EurekAlert

As reported in Advanced Photonics, a team from Huazhong University of Science and Technology (HUST) employed polymer-assisted thermal doping to fabricate RE-doped microcavities with ultrahigh intrinsic Q factors exceeding 108. The doping process reportedly do…
