“…The same setup was used for dispersion measurements reported eg. in [38]. All supercontinuum spectra were obtained under pumping from a compact erbium fiber-based femtosecond laser from Menlo Systems (model C-fiber HP), which delivers around 90 fs long, nearly transform-limited, Gaussianshaped pulses, centered at 1560 nm with a repetition rate of 100 MHz.…”

We report on designing, fabrication and experimental characterization of highly nonlinear, tellurite glass photonic crystal fibers with engineered normal dispersion characteristics for coherent supercontinuum generation. Effectively single mode, air-hole lattice fibers, with measured, all-normal dispersion profiles as flat as -10 to -50 ps/mn/km over 1500-2400 nm wavelengths are developed and investigated. Supercontinuum spectra are measured for these fibers, with a spectral width covering 1100-2600 nm wavelengths under pumping with a robust, fixed-wavelength erbium fiber-based femtosecond laser, delivering 90 fs pulses, centered at 1560 nm with peak power below 40 kW. To the best of our knowledge, this is the first engineered microstructured fiber, which due to its high nonlinearity, enables a self-phase modulation and optical wave breaking-based supercontinuum pumped with a turnkey, 40 kW femtosecond laser at spectral widths obtainable with previous all-normal dispersion fiber designs only under pumping with systems delivering peak power in the MW range.

“…The SA was located between the coupler and isolator. The total cavity length was measured as~9.5 m and its cavity group velocity dispersion (GVD) was calculated as -0.64 ps 2 according to the previously measured dispersion values [29,30] The nonlinear transmission of the prepared SA was also measured using lab-made, ~1.5 ps fiber laser with a repetition rate of 24 MHz at 1.93 μm. Figure 4 shows the measured nonlinear transmission with a fitted curve [27]:…”

Bi2Te3 Topological Insulator for Domain-Wall Dark Pulse Generation from Thulium-Doped Fiber Laser

et al. 2019

We have experimentally demonstrated domain-wall (DW) dark pulses from a thulium-doped fiber laser incorporating a topological insulator saturable absorber (SA). The bulk-structured Bi2Te3 was used as the SA, which was constructed on a fiber ferrule platform through the deposition of the Bi2Te3 mixed with distilled water. The DW dark pulses were generated from the thulium-doped fiber laser cavity with a dual wavelength at 1956 nm and 1958 nm. The dark pulse width and the repetition rate were measured as ~10.3 ns and ~20.7 MHz over the pump power of ~80 mW, respectively. To the best of our knowledge, this work is the first demonstrated generation of the DW dark pulse from a thulium-doped fiber laser using nanomaterial-based SA.

“…We then use 3 m of Nufern PM2000D to stretch the soliton and ensure net normal dispersion inside the CPA. We estimated the dispersion of PM2000D using [27] to be 92 ps 2 /km. The stretched pulse then passes a fast-axis blocked PM-isolator (ISO2) with 0.8 dB insertion loss.…”

All-fiber frequency comb at 2 µm providing 1.4-cycle pulses

et al. 2020

View full text Add to dashboard Cite

We report an all-polarization-maintaining fiber optic approach to generating sub-2 cycle pulses at 2 m and a corresponding octave-spanning optical frequency comb. Our configuration leverages mature Er:fiber laser technology at 1.5 m to provide a seed pulse for a thuliumdoped fiber amplifier that outputs 330 mW average power at 100 MHz repetition rate. Following amplification, nonlinear self-compression in fiber decreases the pulse duration to 9.5 fs, or 1.4 optical cycles. Approximately 32 % of the energy sits within the pulse peak, and the polarization extinction ratio is more than 15 dB. The spectrum of the ultrashort pulse spans from 1 m to beyond 2.4 m and enables direct measurement of the carrier-envelope offset frequency using only 12 mW, or ~3.5 % of the total power. Our approach employs only commercially-available fiber components, resulting in a turnkey amplifier design that is compact, and easy to reproduce in the larger community. Moreover, the overall design and self-compression mechanism are scalable in repetition rate and power. As such, this system should be useful as a robust frequency comb source in the nearinfrared or as a pump source to generate mid-infrared frequency combs.
