Extra Loss-free Non-Hermitian Engineered Single Mode Laser Systems
Mohammad H. Teimourpour, Hamed Dalir, Elham Heidari +4
In a laser system non-Hermitian methods such as Parity-Time (PT) Symmetry and Supersymmetry (SUSY) have shown and demonstrated the ability to suppress unwanted lasing modes and, th…
