چکیده
36 LLE Review, Volume 97 Fiber laser and amplifier development in the wavelength region near 1 μm has experienced significant progress owing to the exceptional efficiency and gain bandwidth of ytterbiumdoped fibers.15 In fact, both ytterbium fiber lasers and amplifiers are becoming more attractive than their bulk counterparts due to their confined spatial mode, impressive bandwidth, good pump absorption, ease of alignment, and inherent compatibility with optical fiber. To date, however, experimental efforts regarding ytterbium fiber lasers have been directed only toward fundamental mode-locking, which typically limits pulse repetition rates below 100 MHz.15

Tunable, high-repetition-rate, harmonically mode-locked ytterbium fiber laser.
We report a ytterbium fiber laser mode locked at its 281st harmonic, which corresponds to a repetition rate greater than 10 GHz. The laser produces linearly polarized, 2-ps pulses with up to 38-mW of average output power. The mode-locked pulses are tunable over a 58-nm window centered on 1053 nm.
متن کاملPicosecond to femtosecond pulses from high power self mode-locked ytterbium rod-type fiber laser.
We have designed an ytterbium rod-type fiber laser oscillator with tunable pulse duration. This system that delivers more than 10 W of average power is self mode-locked. It yields femtosecond to picosecond laser pulses at a repetition rate of 74 MHz. The pulse duration is adjusted by changing the spectral width of a band pass filter that is inserted in the laser cavity. Using volume Bragg grati...
متن کاملTunable all-fiber dissipative-soliton laser with a multimode interference filter.
We report on a tunable all-fiber dissipative-soliton laser with a multimode interference filter that consists of a multimode fiber spliced between two single-mode fibers. By carefully selecting the fiber parameters, a filter with a central wavelength at 1032 nm and a bandwidth of 7.6 nm is constructed and used for spectral filtering in an all-normal-dispersion mode-locked ytterbium-doped fiber ...
متن کاملHigh-repetition-rate mode-locked Er-doped fiber lasers by harmonic injection locking.
We present a novel method for the generation of synchronized short pulses at high repetition rates from Erdoped silica fiber lasers. The method employs coupling of an optical pulse train to a passively mode-locked fiber laser. The injected signal repetition rate is slightly detuned from the modal spacing of the fiber laser, such that a subset of the latter modes is injection locked, yielding a ...
متن کاملMode-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...
