Mode-locked ytterbium fiber lasers.
A compact fiber laser is demonstrated with use of a Gires-Tournois compensator and a short length (2-4 cm-long) of highly doped ytterbium (Yb) fiber providing net anomalous group-velocity dispersion. With use of a novel semiconductor saturable absorber mirror based on GaInNAs structure, self-started 1.5-ps-pulse mode-locked operation was obtained at 1023 nm with a repetition rate of 95 MHz. A m...
متن کاملCharacteristics of Q-Switched Cladding-Pumped Ytterbium-Doped Fiber Lasers with Different High-Energy Fiber Designs
We theoretically and experimentally analyze Q-switched cladding pumped ytterbium-doped fiber lasers designed for high pulse energies. We compare the extractable energy from two high-energy fiber designs: 1) singleor few-moded low-NA large mode area (LMA) fibers and 2) large-core multimode fibers, which may incorporate a fiber taper for brightness enhancement. Our results show that the pulse ene...

متن کاملHigh peak power Ytterbium doped fiber amplifiers
1 Abstract We have tested a series of Ytterbium doped large core fibers operating near 10Kpps and producing pulses of approximately 1ns. We have achieved 850μJ/pulse resulting in peak powers in excess of 2MW with 0.4ns pulses and near diffraction limited beams. In another fiber, we have achieved over 1.5mJ/pulse with pulses of 900ps corresponding to 1.65MW of peak power and M of 2.5. In the lat...
متن کاملTEMPERATURE EFFECTS ON THE EMISSION PROPERTIES OF Yb-DOPED FIBERS (Postprint)
Ytterbium-doped fiber lasers are making impressive leaps in power production. Yet in spite of fibers large surface area to volume ratio which is beneficial for cooling, such power inevitably leads to high core temperatures that in turn affect the laser performance. In this letter, the temperature effects on the emission and fluorescence lifetime of ytterbium doped optical fibers are investigate...
