Advanced Optical Fibers for High Power Fiber Lasers

High-Power Single-Frequency Fiber Lasers

Single frequency laser sources are desired in many applications. Various architectures for achieving high power single frequency fiber laser outputs have been investigated and demonstrated. Axial gain apodization can affect the lasing threshold and spectral modal discrimination of DFB lasers. Modeling results show that if properly tailored, the lasing threshold can be reduced by 21% without sac...

High-power widely tunable thulium fiber lasers.

Applications requiring long-range atmospheric propagation are driving the development of high-power thulium fiber lasers. We report on the performance of two different laser configurations for high-power tunable thulium fiber lasers: one is a single oscillator utilizing a volume Bragg grating for wavelength stabilization; the other is a master oscillator power amplifier system with the oscillat...

High control in high power fiber lasers and amplifiers

We discuss fundamental aspects and future prospects of high power fiber lasers and amplifiers with particular attention to high control of cladding-pumped, rare-earth-doped fiber sources in a multitude of regimes. Summary The past few years have seen dramatic advances in fiber laser and amplifier technologies. Fiber lasers of output powers beyond a kilowatt or multi-kilowatt with high beam qual...

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 ...
