We demonstrate simultaneous spatial and arbitrary temporal pulse-shaping with a picosecond Yb-doped fiber laser system generating an output power > 10 W. By using a self-developed feed-back control algorithm on a single polarization optical pulse shaper, we obtained arbitrary complex pulse structures in the time domain with high accuracy and at high power level. Meanwhile, the pulse shaping in...
We demonstrate a wideband tunable, ultrafast fiber laser mode-locked by using a solution deposited and encapsulated black phosphorus (BP) saturable absorber. Stable, picosecond pulses, tunable from 1535 nm to 1565 nm are generated.
Noise-like pulses (NLPs) are of interest as they can provide low temporal coherence, smooth and broad spectra and high brightness. Owing to these merits, NLPs can facilitate many optical sensing applications, such as hybrid interrogation of high-count low reflectivity fiber Bragg grating arrays. In this paper, we report the abnormal NLP evolution in a passively Er-doped mode-locked fibre laser, of...
By leveraging the polarization interference filtering and the gain profile tilting based on polarization-dependent loss tuning, ultrashort pulses at up to four wavelengths are generated covering both 1530 and 1560 windows of the C-band.
We demonstrate an all-normal dispersion ytterbium-doped fiber laser Q-switched by using a solution processed few-layer tungsten disulfide (WS2)-polymer composite saturable absorber at 1030 nm.
We report on a passively mode-locked erbium-doped fiber laser with a repetition rate as low as 1.2 MHz in a strong normal dispersion regime. The laser was mode locked via spectral filtering. It generated a pulse with large and linear chirp that can be dechirped to 430 fs outside the cavity.
We report a simplified mode-locked Er fiber laser in normal dispersion with birefringence filters compared with the one with nonlinear polarization evolution mechanism.
The paper summarizes recent advances in Er and Yb doped mode locked fiber lasers with saturable absorbers such as semiconductor and carbon nanotube saturable absorbers.
We investigated linear-cavity with ultra-low repetition rate Erbium-doped fiber laser mode-locked by a high modulation depth SESAM. Output pulses were highly-chirped, at energy up to 14 nJ and minimum repetition rate was 25 kHz.
We demonstrate the long linear-cavity with ultra-low repetition rate Ytterbium-doped fiber laser mode-locked by a SESAM. Output pulses were highly-chirped, with energies high to 75.2 nJ and minimum repetition rate was 191 kHz.
A 91.4 kHz repetition rate Er-doped dispersion managed mode-locked fiber laser was demonstrated. The pulse energy was amplified to 790 nJ though single stage amplifier.
A long ring-cavity, low repetition rate Yb-doped fiber laser was demonstrated. Pulses with repetition rate of about 381.3 kHz and single pulse energy above 300 nJ were obtained.
