“…The erbium laser transition is considered as a homogeneously broadened two-level system. This program has been validated by numerous comparisons to experimental results, in various configurations (cw or pulsed regime, core pumped Er or clad pumped Er:Yb fibers...), and yields relative errors lower than 20% with respect to the output signal and residual pump powers [12], [13]. The fiber considered here is an LMA fiber with Er:Yb codoping in the same Al:P host as described above, with an absorption of 80 dB/m at λ peak and 300 K, injected with a cw signal P sig = 1 W at λ sig = 1560 nm and pumped at λ pump = 1535 nm.…”

The influence of low temperatures on the performance of a high-power single-frequency fiber laser amplifier is evaluated with a numerical simulation. Cooling the fiber can allow to take advantage of both higher damping of the acoustic waves in the silica glass, and higher laser efficiency. We first report on the measurement of the stimulated Brillouin scattering (SBS) threshold in a silica fiber as a function of the temperature from 300 K down to 77 K. We then present the measurements of small-signal absorption and gain spectra of an erbium doped alumino-phosphosilicate fiber, at room temperature and liquid nitrogen temperature. Based on these data, we derive a numerical study of the combined effects of cooling on the SBS threshold and the amplifier efficiency, and conclude on the interest of this technique for SBS limited high power Er doped fiber amplifiers (EDFA). The temperature increase caused by the pump laser in the fiber core is also addressed.

“…However, narrow linewidth pulsed Master Oscillator Power Fiber Amplifier (MOPFA) are usually limited in peak power by nonlinear effects arising in the fiber such as Stimulated Brillouin Scattering (SBS) to a few 10-100s Watts in standard fibers [1]. Strategies can be used to mitigate nonlinear effects: for example, shortening the amplifying fiber or counter pumping.…”

a b s t r a c tWe present design and performances of several eye-safe high peak power fiber lasers operating either around 1550 nm or 2000 nm. They share the limitations by nonlinear effects either Stimulated Brillouin Scattering for single frequency lasers or Kerr related effects for short pulse amplifiers. Performances above 1 kW peak power for single frequency lasers and 26 nJ for short pulse fiber lasers are reported. The influence of the saturation power of the fibers on the non-linearity is discussed and applied to a comparison between Erbium and Ytterbium co-doped fibers and Thulium doped fibers. The Brillouin gain properties in these fibers are also compared.

“…Narrow linewidth pulsed MOPFA are usually limited in peak power by nonlinear effects arising in the fiber such as Stimulated Brillouin Scattering (SBS) to a few 10s-100s Watts in standard fibers [1]. In single-mode fibers, the SBS threshold is reached when the peak power time length product reaches about 80 W.m.…”

Long range coherent detection wind lidars have many applications in the fields of wind farms and aircraft safety. Fiber laser sources emitting around 1.5µm show key advantages such as versatility, modularity and robustness of alignments to vibrations. However, nonlinear effects such as Stimulated-Brillouin-Scattering limit achievable peak power because of strong fiber core confinement. Wind lidars based on fiber laser technologies thus operate in a regime with low energy per pulse (typically 10µJ-1mJ) and high pulse repetition frequency (typically 5-50kHz). We investigated various technologies to improve peak power in 1.5µm fiber lasers such as special large mode area (LMA) fiber designs or strain management. Integration of a high peak power source in ONERA LICORNE wind lidar enabled to achieve air speed profiles up to record ranges of 16km within 0.1s averaging time.
