  • graphene mode locked wavelength tunable dissipative soliton Fiber Laser
    Applied Physics Letters, 2010
    Co-Authors: Han Zhang, Dingyuan Tang, Randall J Knize, L.m. Zhao
    Abstract:

    Atomic layer graphene possesses wavelength-insensitive ultrafast saturable absorption, which can be exploited as a “full-band” mode locker. Taking advantage of the wide band saturable absorption of the graphene, we demonstrate experimentally that wide range (1570–1600 nm) continuous wavelength tunable dissipative solitons could be formed in an erbium doped Fiber Laser mode locked with few layer graphene.

  • dark pulse emission of a Fiber Laser
    Physical Review A, 2009
    Co-Authors: Han Zhang, L.m. Zhao, Dingyuan Tang, Xiaokang Wu
    Abstract:

    We report on the dark pulse emission of an all-normal dispersion erbium-doped Fiber Laser with a polarizer in cavity. We found experimentally that apart from the bright pulse emission, under appropriate conditions the Fiber Laser could also emit single or multiple dark pulses. Based on numerical simulations we interpret the dark pulse formation in the Laser as a result of dark soliton shaping.

  • dissipative soliton resonance in an all normal dispersion erbium doped Fiber Laser
    Optics Express, 2009
    Co-Authors: Xiaokang Wu, Dingyuan Tang, Han Zhang, L.m. Zhao
    Abstract:

    We report on the generation of 281.2 nJ mode locked pulses directly from an erbium-doped Fiber Laser mode-locked with the nonlinear polarization rotation technique. We show that apart from the conventional dissipative soliton operation, an all-normal-dispersion Fiber Laser can also emit square-profile dissipative solitons whose energy could increase to a very large value without pulse breaking.

  • observation of high order polarization locked vector solitons in a Fiber Laser
    Physical Review Letters, 2008
    Co-Authors: Dingyuan Tang, L.m. Zhao, Han Zhang, Xiaokang Wu
    Abstract:

    We report on the experimental observation of a new type of polarization-locked vector soliton in a passively mode-locked Fiber Laser. The vector soliton is characterized by the fact that not only are the two orthogonally polarized soliton components phase-locked, but also one of the components has a double-humped intensity profile. Multiple phase-locked high-order vector solitons with identical soliton parameters and harmonic mode locking of the vector solitons were also obtained in the Laser. Numerical simulations confirmed the existence of stable high-order vector solitons in the Fiber Laser.

  • generation of 47 fs pulses directly from an erbium doped Fiber Laser
    Optics Letters, 2007
    Co-Authors: Dingyuan Tang, L.m. Zhao
    Abstract:

    We show both numerically and experimentally that through appropriately selecting the output coupling position and strength in a mode-locked Fiber Laser, one can effectively manage the nonlinearity of the cavity. By implementing the technique together with cavity dispersion management in an erbium-doped Fiber Laser, we have achieved stable mode-locked pulses with a single-pulse energy of 2.08 nJ and pulse width of 46.2 fs directly from the Laser.

  • versatile and widely tunable mid infrared erbium doped zblan Fiber Laser
    Optics Letters, 2016
    Co-Authors: Ori Hendersonsapir, Stuart D. Jackson, D J Ottaway
    Abstract:

    We report on a long wavelength emitting rare earth doped Fiber Laser with the emission centered at 3.5 μm and tunable across 450 nm. The longest wavelength emission was 3.78 μm which is the longest emission from a Fiber Laser operating at room temperature. In a simple optical arrangement employing dielectric mirrors for feedback, the Laser was capable of emitting 1.45 W of near diffraction limited output power at 3.47 μm. These emission characteristics complement the emissions from quantum cascade Lasers and demonstrate how all infrared dual wavelength pumping can be used to access high lying rare earth ion transitions that have previously relied on visible wavelength pumping.

  • high power 83 w holmium doped silica Fiber Laser operating with high beam quality
    Optics Letters, 2007
    Co-Authors: Stuart D. Jackson, Alexander Hemming, Alex Sabella, Shayne Bennetts, David G Lancaster
    Abstract:

    A high-power 83W cladding-pumped Tm3+-Ho3+-doped silica Fiber Laser is reported. Using bidirectional 793nm diode pumping, a maximum slope efficiency of 42% was produced after a threshold launched pump power of 12W was exceeded. The Laser operated at wavelengths near 2105nm with moderate beam quality, i.e., M2∼1.5. Further power scaling of the Fiber Laser was limited by thermal failure of the Fiber ends.

  • microstructured polymer Fiber Laser
    Optics Letters, 2004
    Co-Authors: Alexander Argyros, Martijn A Van Eijkelenborg, Stuart D. Jackson, Richard P. Mildren
    Abstract:

    A microstructured polymer optical Fiber doped with Rhodamine 6G dye was fabricated and demonstrated as an optical amplifier and a Fiber Laser. As an amplifier, the Fiber achieved a gain in excess of 30 dB. As a pulsed Fiber Laser, the Fiber exhibited a threshold of 20 µJ, a slope efficiency of 18%, and a lifetime as high as 130,000 shots at 10 Hz. The maximum output energy was 16 µJ. The advantages that such Fibers offer lie in the simplicity and flexibility of their fabrication and in their potential for use as compact, tunable solid-state sources.

  • single transverse mode 2 5 w holmium doped fluoride Fiber Laser operating at 2 86 μm
    Optics Letters, 2004
    Co-Authors: Stuart D. Jackson
    Abstract:

    A high-power tandem-pumped Ho3+,Pr3+-doped ZBLAN Fiber Laser is demonstrated. Using the free-running 1100-nm output from a diode-cladding-pumped Yb3+-doped silica Fiber Laser as the pump source, a maximum output power of 2.5 W was generated at a slope efficiency of 29% after the threshold of ∼30 mW was reached. Saturation of the output is avoided with Pr3+ codoping, which allows single-transition output. The center wavelength of the output was 2.86 µm and the bandwidth at maximum power was ∼15 nm.

  • high power diode cladding pumped tm doped silica Fiber Laser
    Optics Letters, 1998
    Co-Authors: Stuart D. Jackson, Terence A King
    Abstract:

    The operation of a diode-pumped Tm-doped silica Fiber Laser that uses the cladding-pumping arrangement to produce high-power cw output at wavelengths near 2 µm is reported. We obtained a maximum output power of 5.4 W at a slope efficiency of 31% with respect to the launched pump power at a total optical-to-optical efficiency of 22%. The Fiber-Laser output wavelength was tuned between 1.880 and 2.033 µm by adjustment of the Fiber length, with >4 W of power obtainable from 1.94 to 2.01 µm. Self-pulsations detected in the output from the double-clad Fiber Laser may indicate the presence of ion-clustering effects.

  • Large energy soliton erbium-doped Fiber Laser with a graphene-polymer composite mode locker
    Applied Physics Letters, 2009
    Co-Authors: Han Zhang, Qiaoliang Bao, Luming Zhao, Dingyuan Tang, Kian Ping Loh
    Abstract:

    Due to its unique electronic property and the Pauli Blocking Principle, atomic layer graphene possesses wavelength-independent ultrafast saturable absorption, which can be exploited for the ultrafast photonics application. Through chemical functionalization, a graphene-polymer nanocomposite membrane was fabricated and firstly used to mode lock a Fiber Laser. Stable mode locked solitons with 3 nJ pulse energy, 700 fs pulse width at the 1590 nm wavelength have been directly generated from the Laser. We show that graphene-polymer nanocomposites could be an attractive saturable absorber for high power Fiber Laser mode locking.
