Comparative Study of Ultra-Narrow-Mode Generation in Random Fiber Lasers Based on Different Fiber Types
We studied the properties of ultra-narrow spectral modes, appearing in random distributed feedback Raman fiber lasers, for different fibers building up a laser cavity. Fibers with different nonlinear coefficients and dispersion were employed to obtain the generation. Ultra-narrow modes were observed...

| description | We studied the properties of ultra-narrow spectral modes, appearing in random distributed feedback Raman fiber lasers, for different fibers building up a laser cavity. Fibers with different nonlinear coefficients and dispersion were employed to obtain the generation. Ultra-narrow modes were observed in all fibers except those with the smallest dispersion. We measured the mode parameters, such as the average lifetime, as well as the maximum averaged output power that can support the ultra-narrow generation. The comparison revealed that the modes were more pronounced in high-dispersion fibers. Based on this comparative study, we conclude with the importance of the nonlinearity-dispersion interplay for regime stability. |
