چکیده
• The widely-tunable harmonic mode-locked fiber laser with a fixed repetition rate. Pulse width is tunable by exploiting the combination of spectral filtering and gain management. broadband CNT SA TF play an important role in pulse tunability. Controlled flexible ultrafast pulses are great importance many application fields, such as metrology. Here, we report compact passively effect achieved adopting bandwidth filter, resulting changing order (i.e., rate). On other hand, management can tune order, while emission typically remains same. Thus, these two effects make broad range at At 6th-order mode-locking (76.8 MHz), be tuned from ∼ 0.8 ps to 4.3 adjusting pump strength. development sources high-repetition rate would find potential applications fields optical sensing biomedical imaging.

Widely tunable Tm-doped mode-locked all-fiber laser
We demonstrated a widely tunable Tm-doped mode-locked all-fiber laser, with the widest tunable range of 136 nm, from 1842 to 1978 nm. Nonlinear polarization evolution (NPE) technique is employed to enable mode-locking and the wavelength-tunable operation. The widely tunable range attributes to the NPE-induced transmission modulation and bidirectional pumping mechanism. Such kind of tunable mode...
متن کاملStrong spectral filtering for a mode-locked similariton fiber laser.
We propose a novel mode-locked fiber laser design that relies on attracting similariton solutions in fiber amplifiers with normal group-velocity dispersion and strong spectral filtering to compensate increased pulse duration and bandwidth. Stable high-energy, large-bandwidth pulses are obtained that can be linearly compressed, resulting in ultrashort pulses.

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.

We propose and demonstrate a novel fiber-optic gyroscope in the form of a mode-locked laser consisting of a laser cavity formed by a planar mirror at one end, a gain medium, and a Sagnac interferometer at the other end. The Sagnac interferometer serves as a reflector as well as a rotation-sensing element. The output of the gyroscope is a series of short optical pulses. The separation of two set...
متن کاملTunable and switchable dual-wavelength Tm-doped mode-locked fiber laser by nonlinear polarization evolution.
We propose and demonstrate a tunable and switchable dual-wavelength ultra-fast Tm-doped fiber laser. The tunability is based on nonlinear polarization evolution (NPE) technique in a passively mode-locked laser cavity. The NPE effect induces wavelength-dependent loss in the cavity to effectively alleviate mode competition and enables the multiwavelength mode locking. The laser exhibits tunable d...
