Abstract
Abstract
We present the results for two tantalum borides (TaB and TaB2) as potential saturable absorbers for Q-switched lasers. When incorporated to a ring ytterbium laser operating at 1080 nm, they produced pulse widths as short as 345 ns.

Abstract
Abstract
A nanolaser using AlGaAs nanodisk is theoretically demonstrated based on anapole state. The radius and height of the nanodisk are optimized to be 240nm and 120nm through geometry tuning based on Mie scattering theory. We have achieved near-field lasing at 1017nm with linewidth around 3.5nm.
