“…However, in several CW pumped rare-earth doped fiber lasers, self-pulsation in the output power for different resonator configurations and pumping geometries have been reported [1][2][3][4][5][6][7][8][9][10]. Two types of self-pulsations in fiber lasers are reported in the literature: sustained self-pulsing (SSP) and self-mode locking (SML) [8]. SSP is the emission of high intensity pulses at irregular intervals, whereas SML is the laser signal modulation or pulse spiking in the output with period corresponding to the cavity round-trip time.…”

“…There has also been substantial effort to reduce self-pulsing. The reported techniques to suppress self-pulsing include use of unidirectional fiber ring cavity [1,8], use of a low transmission output coupler giving a high Q-cavity [1], resonant pumping near the lasing wavelength to prevent rapid depletion of gain [24,25], thereby minimizing relaxation oscillations, electronic feedback to the pump laser to shift the gain and phase [26], increasing round-trip time in the cavity by adding a long section of passive fiber to change the relaxation oscillation dynamics [27], using fast saturable gain of a semiconductor optical amplifier within the fiber laser cavity [28] and use of the narrow pass-band of a k/4-shifted FBG structure in a ring cavity to limit the number of longitudinal cavity modes [29].…”

“…Notice that self-pulsing instabilities in YFL are known and extensively treated (see, e.g., [13,14]), but their physical origin stays still unclear [14]. Everywhere the reported results scope instabilities in YFL, not stable SQS YFL operation that is the main result of the present research.…”

Abstract:We report an experimental realization and study of a self-Q-switched diode-pumped all-fiber Ytterbium laser. Possible mechanisms leading to establishing of self-Q-switching in the laser are discussed. Pulsed Ytterbium-doped fiber lasers operating near 1 µm are currently of increased interest as the devices potentially applicable in different areas of technology, medicine, basic research, etc. Rather than mode-locked Ytterbium fiber lasers generating ultra-short pulses (of femto-or pico-second duration), Q-switched Ytterbium fiber lasers oscillate normally pulses of nano-or submicrosecond duration ("giant pulses"). Usually the giant-pulse regimes can be realized in Ytterbium fiber lasers applying the Q-switching techniques conventional for bulk lasers, using as Q-switches acousto-or electro-optical elements, or solid-state saturable absorbers [1][2][3][4][5]. Apparently, the integrated fiber-bulk architecture of such laser schemes is a disadvantage in majority of applications. That is why implementation of Q-switched all-fiber Ytterbium lasers generating stable and powerful short pulses becomes an important point of current researches. To date, only a couple of actively Q-switched all-fiber Ytterbium laser designs have been proposed [6,7]. Meanwhile, the Q-switching arrangements in these lasers are complicate and expensive: As in all actively Q-switched lasers, additional electronic and optical circuits are needed to be incorporated in a laser scheme. So, more attention is paid now to develop passively Q-switched Ytterbium all-fiber lasers as an alternative to the actively Q-switched ones. The passive Qswitching methods to realize such lasers [8][9][10][11] have obvious potential advantages -the simplicity of implementation, low cost, and insensitivity to the environmental influences. However, there are also very few designs for passively Q-switched all-fiber Ytterbium lasers. Virtually in all these lasers the Brillouin or Raman scattering are exploited as the switching mechanisms [8][9][10]. The main drawback of the mentioned lasers is their quite instable operation that seems to stem from the stochastic nature of the Q-switching nonlinear scatterings, while giant pulses generated are quite short (nanoseconds) and powerful.

“…In a cavity, such a phenomenon is fully exacerbated, so that slow dynamics such as gain transient effects are known to significantly affect the formation of ultrashort pulse structures down to the picosecond time range [41]. Gain saturation alone has been used to explain self mode locking with nanosecond pulse formation [42]. It is therefore essential not to confuse the buildup time of structures, which can take thousands of cavity round-trips, with the duration of typical pulse structures.…”

Dynamics of the transition from polarization disorder to antiphase polarization domains in vector fiber lasers

We demonstrate that nonlinear polarization coupling in a fiber ring laser without polarization-selective elements, subject to the effects of average anomalous dispersion, Kerr effect, and nonlinear gain saturation, can lead to the antisynchronization of spatiotemporal chaos into a wide variety of ordered laminar states of orthogonal polarization temporal domains. These antiphase polarization domains include stable lattices of soliton trains with high duty cycle at repetition rates of hundreds of MHz, as well as sparse trains of coupled dark and bright solitary waves.
