Mid‐infrared Frequency‐Swept Laser at 50 MScans/s Via Frequency Down‐Conversion of Time‐Stretched Near‐Infrared Pulses

Laser &Photonics Reviews, EarlyView.
A mid‐infrared frequency‐swept source operating is presented at 50 MScans s−1 using frequency down‐conversion of time‐stretched 1.5‐µm pulses generated from an Er‐doped mode‐locked fiber laser. The developed source enables high‐resolution gas‐phase MIR spectroscopy with a bandwidth of 15 cm−1 and a resolution of 0.086 cm−1 at a measurement rate of 50 ...

3D Dielectric Chiral Metamaterials Achieving Nondispersive Near‐Zero Ellipticity

Laser &Photonics Reviews, EarlyView.
Broadband and high‐transmission‐efficiency optical activity (OA) is a critical functionality for numerous applications but is challenging to achieve. By engineering circularly polarized (CP) eigenstates in three‐dimensional (3D) dielectric helices, a 3D‐printed ceramic metamaterial is demonstrated for broadband OA with nondispersive near‐zero ...

Dynamics of Dissipative Cavity Solitons in a Lattice Trap

Laser &Photonics Reviews, EarlyView.
This work presents a generalized analytical model elucidating the dynamics of dissipative solitons in dual‐frequency‐pumped Kerr‐nonlinear cavities. The unified framework predicts new phenomena and expounds hitherto unexplained experiments covering hysteresis, Arnold tongues, and existence region of all‐optical dissipative time crystals.
