Abstract

The proportionality factor K, defined as the ratio of the damping rate γ to the square of resonance frequency f02, is an important parameter which may limit the maximum possible intrinsic bandwidth of lasers.1 This maximum possible 3-dB bandwidth f3dBmax is simply given by f3dBmax=8.8/K. The intrinsic bandwidth limit of single and multimode lasers can be evaluated by measuring their K values.
