Laser &Photonics Reviews, Volume 17, Issue 12, December 2023., 2023 Hyperspectral Coherent Raman Scattering microscopy is capable of distinguishing molecules in complex heterogeneous systems by probing multiple Raman resonances. A rapidly tunable two‐color fiber laser is demonstrated. The superior noise performance of this system is evaluated by the side‐by‐side comparison with data from a commercial optical parametric

Emerging 2D Materials with Nonparabolic Bands for Ultrafast Photonics
Small Science, Volume 3, Issue 10, October 2023., 2023 Materials with nonparabolic bands focus on different applications in ultrafast photonics, such as ultrafast carrier dynamics and nonlinear optical response. Linear dispersive Dirac bands have massless electrons like a photon, while nondispersive flat bands host electrons with an infinite mass.

860 femtoseconds mode-locked fiber laser by Gallium co-doped erbium fiber (Ga-EDF)
Results in Physics, 2019 We proposed and demonstrated a high power mode-locked fiber laser using a new type of gain medium which is called as Erbium Gallium co-doped fiber (Ga-EDF). The mode-locking mechanism is enabled by a graphene-based saturable absorber, which is fabricated

Chaotic Internal Dynamics of Dissipative Optical Soliton Molecules
Laser &Photonics Reviews, Volume 17, Issue 8, August, 2023., 2023 Can the analogy between optical soliton molecules and matter molecules be further developed? Do optical soliton molecules allow low‐dimensional chaos? An ultrafast fiber laser experiment with advanced characterization demonstrates bifurcations leading to chaotic relative motions of the bound optical solitons.
