Self−Mode−Locked 2−μm GaSb−Based Optically Pumped Semiconductor Disk Laser
Applied Sciences, 2023 We present a mode−locked GaSb−based optically pumped semiconductor disk laser operating at 2 µm based on the self−mode−locked mechanism. Using the delay differential equation model, we discuss the influence of cavity length on the stability of self−mode ...

Interaction of two magnetic micro-chains in a rotating field
AIP Advances, 2020 Interactions between two chains consisted of micro-sized magnetic beads are experimentally investigated. Driven by a rotating field, three distinct modes of magnetic interactions are identified, referred to as chaining, locking and transit.

Spatiotemporally mode-locked soliton fiber laser at 2.8 μm
High Power Laser Science and Engineering, 2023 Spatiotemporal mode-locking creates great opportunity for pulse energy scaling and nonlinear optics research in fiber. Until now, spatiotemporal mode-locking has only been realized in normal-dispersion dissipative soliton and similariton fiber lasers. In

Mode locking in an optomechanical cavity [PDF]
EPL (Europhysics Letters), 2020 We experimentally study a fiber-based optical ring cavity integrated with a mechanical resonator mirror and an optical amplifier. The device exhibits a variety of intriguing nonlinear effects including synchronization and self-excited oscillation. Passively generated optical pulses are observed when the frequency of the optical ring cavity is tuned ...

PT-symmetric mode-locking [PDF]
Optics Letters, 2016 Parity-time ($\mathcal{PT}$) symmetry is one of the most important accomplishments in optics over the past decade. Here the concept of $\mathcal{PT}$ mode-locking of a laser is introduced, in which active phase locking of cavity axial modes is realized by asymmetric mode coupling in a complex time crystal. $\mathcal{PT}$ mode-locking shows a transition

Irrational mode locking in quasiperiodic systems [PDF]
, 2007 A model for ac-driven systems, based on the Tang-Wiesenfeld-Bak-Coppersmith-Littlewood automaton for an elastic medium, exhibits mode-locked steps with frequencies that are irrational multiples of the drive frequency, when the pinning is spatially ...
