Comparison of Different Linewidth Measuring Methods for Narrow Linewidth Laser

Sensors, 2022
We experimentally demonstrate a fiber laser with different linewidths based on self-injection locking (SIL) and the stimulated Brillouin scattering effect.

Linewidth for fluxon oscillators

Physical Review B, 1982
Soliton perturbation theory is used to calculate the fluxon oscillator linewidth arising from fluxon interaction with background radiation. Detailed calculations in the case of an oscillator that is long compared with the Josephson length and for which the radiation field is thermal establish lower bounds for the linewidth of a real oscillator.

Homogeneous linewidth and linewidth enhancement factor for a GaAs semiconductor laser

Journal of Physics D: Applied Physics, 1986
The homogeneous linewidth and the linewidth enhancement factor alpha for a room-temperature GaAs laser are studied, calculating the time constant for the relaxation of the polarisation. The homogeneous linewidth obtained, arising from electron-electron and electron-phonon interactions, is of the order of several meV.
