GaSb-based angled cavity semiconductor lasers
2022 28th International Semiconductor Laser Conference (ISLC)（2022）
Abstract
Angled cavities can suppress filamentation in mid-IR broad area diode lasers we fabricated, but some high order modes still exist. By removing certain regions that don't contribute gain to the fundamental mode, we demonstrate improved beam quality, and a ~2 fold brightness enhancement.
