“…The model describes spectral broadening during one round trip and the building of a steady state over many round trips. We integrated equations (M2) along z using the split-step Fourier transform method and an iterative procedure similar to that used for modeling of Brillouin fibre lasers [34]. For example, to integrate the equation for As,p±(z,t), we substituted into the equation As,p∓(z,t) obtained on a previous iteration and so on.…”

An important group of nonlinear processes in optical fibre involves the mixing of four waves due to the intensity dependence of the refractive index. It is customary to distinguish between nonlinear effects that require external/pumping waves (cross-phase modulation and parametric processes such as four-wave mixing) and self-action of the propagating optical field (self-phase modulation and modulation instability). Here, we present a new nonlinear self-action effect, self-parametric amplification (SPA), which manifests itself as optical spectrum narrowing in normal dispersion fibre, leading to very stable propagation with a distinctive spectral distribution. The narrowing results from an inverse four-wave mixing, resembling an effective parametric amplification of the central part of the spectrum by energy transfer from the spectral tails. SPA and the observed stable nonlinear spectral propagation with random temporal waveform can find applications in optical communications and high power fibre lasers with nonlinear intra-cavity dynamics.

“…Stimulated Brillouin Scattering (SBS) is the nonlinear process with the lowest threshold in optical fibers [1]. SBS in optical fiber is very valuable for numerous applications such as fiber lasers, fiber amplifiers, fiber sensors, and optical processing of radio-frequency signals [2][3][4][5][6][7][8][9]. very promising for a variety of special uses, such as coherent interferometric sensing, optical communication, microwave photonics, and coherent radar detection [11][12][13].…”

We consider ultra narrow-line lasers based on doubly-resonant fiber cavities, describe experimental techniques, and present two methods for passive stabilization of single-frequency fiber "rillouin lasers. In the first approach, "rillouin fiber laser is passively stabilized at the pump resonance frequency by employing the self-injection locking phenomenon. We have demonstrated that this locking phenomenon delivers a significant narrowing of the pump laser linewidth and generates the Stokes wave with linewidth of about . kHz. In the second methodology, the fiber laser is stabilized with an adaptive dynamical grating self-organized in un-pumped Er-doped optical fiber. The laser radiates a single-frequency Stokes wave with a linewidth narrower than Hz. The ring resonators of both presented lasers are simultaneously resonant for the pump and the Stokes radiations. For adjusting the double resonance at any preselected pump laser wavelength, we offer a procedure that provides a good accuracy of the final resonance peak location with ordinary measurement and cutting errors. The stable regime for both "rillouin lasers is observed during some intervals, which are interrupted by short-time jumping-intervals. The lasers' stability can be improved by utilizing polarization-maintaining PM fiber configuration and a cavity protection system.

“…For a monochromatic pump at 1550 nm, the Brillouin gain factor is almost three orders of magnitude higher than the Raman gain, providing amplification with a bandwidth of ~35 MHz and a frequency down-shift of ~11 GHz from the pump frequency (see Figure1). Therefore, Brillouin gain is commonly used for narrow-band lasing in fiber configurations enabling a variety of the performance characteristics [1][2][3][4][5][6][7][8][9].…”

Single longitudinal-mode Brillouin fiber lasers are very promising for many applications, such as coherent optical communication, interferometric sensing, coherent radar detection, and microwave photonics. In the lasers with doublyresonant cavities Stokes wave is generated by a short fiber ring cavities that are simultaneously resonant for pump and Stokes radiation. Therefore, such lasers emit coherent light in two laser lines separated by the Brillouin shift. We report a simple procedure allowing precise adjustment of the Brillouin fiber ring cavities for doubly-resonant operation and demonstrate two completely passive solutions enabling perfect stabilization of such cavities for generation of doublefrequency light. In our experiments, the first laser configuration is stabilized through self-injection locking mechanism implemented to the laser cavity with DFB semiconductor pump laser. Second configuration comprises a nonlinear fiber mirror based on the population inversion dynamical gratings induced in low-absorbed Er-doped fiber. The pump-toStokes conversion efficiency of ~40% in both cases and the Stokes linewidth of <500Hz for the first case and < 100Hz for the second are successfully demonstrated.
