3C Yb-doped Fiber Based High Energy and Power Pulsed Fiber Lasers

چکیده
3C fiber technology advances the performance frontier of practical, high-pulse-energy fiber lasers by providing very large core fibers with the handling and packaging benefits associated with single mode fibers. First-generation fibers demonstrate scaling to > 240 W average power coincident with 100-kW peak power in 1-mJ, 10-ns pulses while maintaining single-mode beam quality, polarized output, and efficiencies > 70%. Peak powers over 0.5 MW with negligible spectral distortion can be achieved with sub ns, near-transform-limited pulses. In-development secondgeneration 3C Yb-fiber based on core sizes around 55 μm 1 have produced >8 mJ, 13 ns pulses with peak powers exceeding 600 kW.

All fiber-based Yb-doped high energy, high power femtosecond fiber lasers.
Two all fiber-based laser systems are demonstrated to achieve high energy and high average power femtosecond pulsed outputs at wavelength of 1 µm. In the high energy laser system, a pulse energy of 1.05 mJ (0.85 mJ after pulse compressor) at 100 kHz repetition rate has been realized by a Yb-doped ultra large-core single-mode photonic crystal fiber (PCF) rod amplifier, seeded with a 50 µJ fiber ...

There is worldwide considerable interest in the study and development of high-power Yb-doped continuous wave (CW) and pulsed fiber lasers for various material processing applications. Although it appears to be trivial to generate high-power CW output from Yb-doped CW fiber lasers by pumping with high-power CW laser diodes; however, it is not so easy to generate truly CW output without amplitude...

We numerically model the performance of highpower 977-nm fiber lasers and amplifiers pumped at 915 nm, in which the Yb is doped in a ring inside the core of a high-ordermode (HOM) fiber. Light in the spatially coherent LP07 mode is amplified in the fiber, and then coupled to the LP01 mode by longperiod gratings. For the laser, it is found that parasitic oscillation on the 1023-nm four-level tra...
