Quantum limit of the laser linewidth in chaotic cavities and statistics of residues of scattering matrix poles
H. Schomerus, K. M. Frahm, M. Patra +1
The quantum-limited linewidth of a laser cavity is enhanced above the Schawlow-Townes value by the Petermann factor K, due to the non-orthogonality of the cavity modes. We derive t…

Large Petermann factor in chaotic cavities with many scattering channels
K. Frahm, H. Schomerus, M. Patra +1
The quantum-limited linewidth of a laser cavity is enhanced above the Schawlow-Townes value by the Petermann factor K, due to the non-orthogonality of the cavity modes. The average…

Quantum-limited linewidth of a chaotic laser cavity
M. Patra, H. Schomerus, C. W. J. Beenakker
A random-matrix theory is presented for the linewidth of a laser cavity in which the radiation is scattered chaotically. The linewidth is enhanced above the Schawlow-Townes value b…
