Tunable and switchable all-fiber dual-wavelength mode locked laser based on Lyot filtering effect.
Optics Express, 2019 Mode-locked fiber lasers that generate two frequency combs with different frequency intervals could find very important applications in low-complexity dual-comb metrology. We report a partially polarization-maintaining all-fiber dual-wavelength dual-comb

Harmonically mode-locked Ti:Er:LiNbO_3 waveguide laser [PDF]
Optics Letters, 1995 Active mode locking of an Er-diffusion-doped Ti:LiNbO(3) waveguide laser by intracavity phase modulation to as high as the fourth harmonic (5.12 GHz) of the axial-mode frequency spacing is reported. The diode-pumped, pigtailed, and fully packaged laser with a monolithically integrated intracavity phase modulator has a threshold of 9 mW (incident pump ...

Stability calculations for the ytterbium-doped fiber laser passively mode-locked through nonlinear polarization rotation [PDF]
, 2004 We investigate theoretically a fiber laser passively mode-locked with nonlinear polarization rotation. A unidirectional ring cavity is considered with a polarizer placed between two sets of a halfwave plate and a quarterwave plate.

WS2 mode-locked ultrafast fiber laser [PDF]
Scientific Reports, 2015 Graphene-like two dimensional materials, such as WS2 and MoS2, are highly anisotropic layered compounds that have attracted growing interest from basic research to practical applications. Similar with MoS2, few-layer WS2 has remarkable physical properties. Here, we demonstrate for the first time that WS2 nanosheets exhibit ultrafast nonlinear saturable

Triple-wavelength fiber ring laser based on a hybrid gain medium actively mode-locked at 10 GHz [PDF]
, 2008 A fiber ring laser based on a hybrid gain medium that produces three simultaneously mode-locked wavelength channels is presented. The lithium niobate based modulator used to actively mode-lock the laser cavity at 10 GHz is birefringence compensated to ...

Generation of chirp-free picosecond pulses [PDF]
, 1977 The frequency spectrum of moderately chirped laser pulses depends upon the portion of the beam which is accepted by the spectrometer. Observation of the development of the chirp in a mode-locked pulse train allows to determine the small incipient chirp ...

Pulse shortening in an actively mode-locked laser with parity-time symmetry
APL Photonics, 2018 We consider an actively mode-locked laser system with parity-time symmetry. The system consists of two ring cavities, each incorporating an amplitude modulator operating at the same modulation frequency, but with the modulation phases differing by π.
