Tm-doped mode-locked fiber lasers
Optical Fiber Technology, 2014Abstract Ultrashort pulse fiber lasers are increasingly used in various areas for scientific as well as industrial purposes. In contrast to ultrashort pulse lasers based on ytterbium- and erbium-doped fibers, the dispersion of silica fibers in the amplification band of thulium-doped fibers around 2 μm is typically anomalous, which has fundamental ...

Stabilizing Harmonically Mode-Locked Fiber Laser
2007 IEEE International Conference on Signal Processing and Communications, 2007Applications of ultra short pulses in optical signal processing, communications and high speed electronics have grown rapidly in recent years. However, high stability of the generated pulses is of prime importance for these applications. This paper describes the quantitative stability analysis of optical pulses generated through passively mode locked ...

Passive mode-locked fiber ring laser
2010 Photonics Global Conference, 2010In this paper, simulation of a classical passive mode-locked fiber ring laser model is given first to investigate the variation of the output parameters with different dispersion and nonlinear effects. After it, an experiment based on Carbon Nanotube (CNT) saturable absorber is carried out with a newly-developed device integrating multiple functions ...

Multi-wavelength mode-locked fiber laser
Proceedings of SPIE, 2006In this paper, we demonstrate a novel stabilization scheme of actively harmonically mode-locked Erbium-doped fiber lasers (ML-EDFLs) by using highly nonlinear fibers in the cavity. 2 and 4 wavelengths anchored on ITU-T standards with 100 GHz channel spacing are successfully generated without gain competition. The amplitude fluctuation and timing jitter

Graphene mode locked ultrafast fiber lasers
SPIE Proceedings, 2011We demonstrate experimentally that few atomic layer graphene possesses ultrafast, super broadband saturable absorption, which can be exploited to passive mode lock fiber lasers of different operation wavelengths. Passive mode locking performance of an erbium-doped fiber laser operating at the 1.55μm and an ytterbium-doped fiber laser operating at ...

All-fiber bidirectional passively mode-locked ring laser
Optics Letters, 2007We report the design and operation of a novel all-fiber bidirectional passively mode-locked ring laser. An erbium-doped fiber was chosen as the active element in a ring cavity arrangement. A short segment of a fiber taper embedded in carbon nanotubes/polymer composite, acting as a saturable absorber, was used to enable bidirectional mode locking.

Review of mode-locked fiber lasers
Proceedings of Optical Fiber Communication Conference (, 1997The interest in mode-locked fiber lasers goes beyond the interesting physics that can be observed in their operation. There are a number of potential operating characteristics that make them particularly attractive and as a result a large number of designs have been examined, attempting to optimize the operation of the laser to suit the particular ...

Asynchronous Mode Locking of Fiber Lasers
2000Abstract : This project resulted in the development of several novel optical fiber lasers designed to generate short pulses for optical communication networks and for optical signal processing. The concept of using asynchronous modulation for stable soliton generation was developed and extended successfully to optical memory loops.
