Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity

Laser &Photonics Reviews, EarlyView.
A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

NIR/VIS Dual‐Comb Spectroscopy Comparing High and Low Repetition Rate Regimes

Laser &Photonics Reviews, EarlyView.
This work compares dual‐comb spectroscopy at lower and higher repetition rates, emphasizing the inherent trade‐off between spectral and temporal resolution. The 80 MHz system provides high‐resolution spectra suitable for analyzing complex molecular structures, whereas the free‐running 1 GHz platform enables fast measurements for real‐time trace gas ...

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

Laser &Photonics Reviews, EarlyView.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Optical‐to‐Microcomb Stability Transfer for Ultrastable Timing and Microwave/Millimeter‐Wave Generation

Laser &Photonics Reviews, EarlyView.
This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.
