Hyperspectral Coherent Raman Scattering (CRS) Microscopy Based on a Rapidly Tunable and Environmentally Stable Fiber Laser

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.
