“…Frontier applications, however, have a high demand for HPFFLs at 1.5 m, for example, high-aspect-ratio through-silicon-vias fabrication [ 11 ] and corneal surgery [ 12 , 13 ] . Moreover, HPFFLs at 1.5 m are promising drive sources for frequency conversions through second-harmonic generation [ 14 , 15 ] , Cherenkov radiation [ 16 ] , soliton self-frequency shift (SSFS) [ 17 , 18 ] and self-phase modulation [ 19 ] , to name just a few. In general, the average-power (or pulse-energy) scaling of the 1.5- m fs fiber laser is mainly based on chirped pulse amplification (CPA) [ 20 ] .…”

In this work, we present a high-power, high-repetition-rate, all-fiber femtosecond laser system operating at 1.5 $\unicode{x3bc}$ m. This all-fiber laser system can deliver femtosecond pulses at a fundamental repetition rate of 10.6 GHz with an average output power of 106.4 W – the highest average power reported so far from an all-fiber femtosecond laser at 1.5 $\unicode{x3bc}$ m, to the best of our knowledge. By utilizing the soliton-effect-based pulse compression effect with optimized pre-chirping dispersion, the amplified pulses are compressed to 239 fs in an all-fiber configuration. Empowered by such a high-power ultrafast fiber laser system, we further explore the nonlinear interaction among transverse modes LP01, LP11 and LP21 that are expected to potentially exist in fiber laser systems using large-mode-area fibers. The intermodal modulational instability is theoretically investigated and subsequently identified in our experiments. Such a high-power all-fiber ultrafast laser without bulky free-space optics is anticipated to be a promising laser source for applications that specifically require compact and robust operation.

“…[3][4][5] Further, the high-power 1560 nm fiber laser can also serve as an alternative for the Ti:Sapphire laser, after converting the central wavelength to 780 nm. 6,7) In recent years, high-power 1560 nm fiber lasers have been widely used in multiphoton bioimaging. 8,9) The femtosecond laser sources operating at the second near-infrared region (NIR-II) can be realized by applying the nonlinear frequency shift with the high-power 1560 nm femtosecond lasers, which are proved to be the ideal laser sources for multiphoton bioimaging.…”

We report on a 13.2-W, 474-fs, 31.12-MHz, all-polarization-maintaining (PM), 1560-nm fiber laser system based on the chirped-pulse amplification (CPA). The home-built seed laser with the nonlinear amplified loop mirror (NALM) can deliver two trains of laser pulses. Two stages of cascaded all-PM Er:Yb co-doped fiber (EYDF) amplifiers were employed in scaling up the average power. The corresponding numerical simulation and experimental investigations were implemented in optimizing the power amplification process. To our knowledge, this is the highest output power ever reported for the 1560-nm femtosecond all-PM fiber laser systems.
