This study attempts to characterize the electromagnetic compromising emanations from Laser Facsimile. Electromagnetic radiation is inevitable when electronic equipment works. The radiations can deteriorate the performance of a part of device itself or of another system. This phenomenon is a subject in the field of electromagnetic compatibility (EMC). But concerning people who process classified information,...
With the improvement of flash memory storage density, data reliability and flash lifetime are decreased. Error correction codes (ECC) and error management schemes can boost both reliability and lifetime. However, in order to develop effective fault tolerance algorithms and management solutions, it is very necessary to have a more profound understanding of failure modes of flash memory. To enable such...
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.
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.
