Deterministic chaos in an ytterbium-doped mode-locked fiber laser
, 2018 We experimentally study the nonlinear dynamics of a femtosecond ytterbium doped mode-locked fiber laser. With the laser operating in the pulsed regime a route to chaos is presented, starting from stable mode-locking, period two, period four, chaos and ...

Pulse forming in an AM mode-locking hybrid TEA-CO2 laser [PDF]
, 1986 We performed an experimental study on the pulse forming mechanism in an AM mode-locked hybrid TEA-CO2 laser by means of “injection mode-locking”. The results show that bandwidth limited pulses will only be reached within a small - critical - range of ...

Mode-locked laser autocollimator with an expanded measurement range.
Optics Express, 2016 A mode-locked laser is employed as the light source of a laser autocollimator, instead of the conventionally employed single-wavelength laser, for an expanded range of tilt angle measurement.

Advanced Functional Materials, EarlyView.This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

Generation of femtosecond light pulses in the near infrared around λ = 850 nm [PDF]
, 1986 Femtosecond light pulses tunable between 840 nm and 880 nm are generated in a synchronously pumped ring dye laser. The laser emits nearly bandwidth-limited pulses (Δv tp = 0.45) with pulse durations down to 65 fs.

Multiband Switchable Microwave Absorbing Metamaterials Based on Reconfigurable Kirigami–Origami
Advanced Functional Materials, EarlyView.A reconfigurable metamaterial featuring tunable microwave‐absorbing and load‐bearing performance is proposed. Stretchable kirigami and bistable origami configurations are integrated as actuating components, and the synergistic deformation mechanisms are systematically analyzed.

Sub-100 fs pulse generation from dispersion-managed mode-locked Er:ZBLAN fiber laser at 2.8 μm
High Power Laser Science and EngineeringWe demonstrate the sub-100 fs pulse generation from a dispersion-managed mode-locked Er:ZBLAN fiber laser at 2.8 μm. Both numerical simulation and experiment demonstrate that stretched-pulse and dissipative soliton mode lockings coexist in the near-zero ...
