Robust watt-level continuous-wave deep-ultraviolet lasers near 230 nm
J. Cai, M. Stoepper, P. Agarwal +20
Continuous-wave (CW) deep-ultraviolet (DUV) lasers near 230~nm enable laser cooling of AlF, Cd, and Zn, but second-harmonic generation below 237~nm relies in practice on beta-bariu…

Highly uniform GaSb quantum dots with indirect-direct bandgap crossover at telecom range
Abhiroop Chellu, Joonas Hilska, Jussi-Pekka Penttinen +1
We demonstrate a new quantum-confined semiconductor material based on GaSb quantum dots (QDs) embedded in single-crystalline AlGaSb matrix by filling droplet-etched nanoholes. The…
