Deep‐UV Photonic Crystal Surface‐Emitting Lasers
Laser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.The first deep‐UV photonic crystal surface‐emitting lasers (PCSELs) at 279 nm are demonstrated under pulsed optical pumping. The PCSELs have single‐mode emission with a 17‐pm linewidth and a divergence angle of less than 1∘$^{\circ }$. Experimental results highlight the impact of the filling factor choice on the lasing mode and the far‐field emission ...
