We numerically investigated noise transfer in ultralong Raman fiber lasers. Noise levels were comparable to other Raman laser types, with distinct spectral characteristics observed.

Area of Science:

  • Optics and Photonics
  • Laser Physics
  • Fiber Optics

Background:

  • Understanding noise transfer is crucial for optimizing laser performance.
  • Random distributed feedback ultralong Raman fiber lasers offer unique properties but require detailed noise analysis.

Purpose of the Study:

  • To numerically investigate the relative intensity-noise transfer from a pump laser to the Stokes component.
  • To compare noise transfer in random distributed feedback ultralong Raman fiber lasers with other configurations.

Main Methods:

  • Numerical simulations were employed to model the ultralong Raman fiber laser system.
  • Analysis focused on the intensity-noise characteristics of the pump and Stokes signals.

Main Results:

  • Relative intensity-noise transfer levels were found to be comparable to distributed Raman amplification and cavity-based ultralong Raman fiber lasers.
  • Unique spectral features associated with the noise transfer were identified.

Conclusions:

  • The study quantifies noise transfer in a specific ultralong Raman fiber laser design.
  • Findings suggest that while noise levels are similar to other systems, unique spectral properties warrant further investigation.
