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.

A WIDEBAND AND FLAT-GAIN OF AN AMPLIFIER BY USING ZIRCONIA-BASED ERBIUM-DOPED FIBER (ZR-EDF) FOR SINGLE PASS PPERATION

Jurnal Teknologi, 2016
An amplification for single pass operation was demonstrated by using Zirconia-based erbium-doped fiber (Zr-EDF). 1 m is the optimum length due to overall high gain and minimal noise figure from 1520 nm to 1620 nm. The highest gain is 28.62 dB at 1555 nm with the input signal and pump power are fixed at -30 dBm and 130 mW, respectively. At input signal -

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.
