Actively mode-locked visible upconversion fiber laser
Optics Letters, 2000Active mode locking of a Pr(3+)/Yb (3+) -doped upconversion fluoride fiber laser with an all-fiber ZnO acousto-optic phase modulator is demonstrated for the first time to the authors' knowledge. Optical pulses of ~550-ps duration with a repetition rate of 239 MHz at a wavelength of 635 nm have been generated.

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 ...

Wideband frequency modulation of a mode-locked fiber laser
Optics Letters, 2004We have demonstrated wideband frequency modulation of the frequency comb lines of a high-repetition-rate fiber laser. With a modulation frequency of only approximately 10 kHz, we have generated modulation indices in excess of 250. Although internally modulated, the laser remains stable with 2-kHz linewidths, and thus the 10-kHz modulation sidebands are

Subpicosecond solitons in an actively mode-locked fiber laser
Optics Letters, 1996Experimental results are presented for a study of the stability regime of an actively mode-locked polarizationmaintaining fiber ring laser used as a memory. Observations indicate that the pulse widths in the memory can be reduced (by soliton effects) by a factor of approximately 4.4 below the pulse widths predicted by standard active mode-locking ...

Bidirectional mode-locked thulium-doped fiber laser
Applied Optics, 2018We report a bidirectional mode-locked thulium-doped fiber laser. Mode-locking is enabled by the combination of semiconductor saturable absorption and nonlinear polarization rotation. Two stable mode-locked picosecond pulse trains in opposite directions are generated with a fundamental repetition rate of ∼16.57 MHz.

High-sensitivity mode-locked fiber laser gyroscope
Optics Letters, 1997We report significant performance improvement of a mode-locked fiber laser gyroscope. A Fabry-Perot cavity GaAlAs laser diode whose front facet was antireflection coated was used as a gain medium. The rms noise equivalent rotation rate measured with a time-interval counter was improved to 0.06deg/ radicalh.

Mode-locked fiber laser based on chalcogenide microwires
Optics Letters, 2015We report the first mode-locked fiber laser using a chalcogenide microwire as the nonlinear medium. The laser is passively mode-locked with nonlinear polarization rotation and can be adjusted for the emission of solitons or noise-like pulses. The use of the microwire leads to a mode-locking threshold at the microwatt level and shortens the cavity ...

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.

Mode Locked Fiber Lasers and Their Applications.
1996Abstract : This work has resulted in the development of a compact self-starting modelocked erbium fiber laser. The remarkable feature is the elimination of the need for any type of polarization control. Furthermore, all of the components are passive and are contained within the fiber cavity medium itself.
