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...
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 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.
381 kHz repetition-rate operation of an Yb-doped fiber laser oscillator and amplifier was demonstrated. The single pulse energy was 734 nJ after the single stage amplification.
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.
