Laser &Photonics Reviews, Volume 20, Issue 3, 5 February 2026.High‐sensitivity, high‐resolution stimulated Raman photoacoustic spectroscopy is achieved by coupling continuous‐wave pump and Stokes beams to a high‐finesse optical cavity. This approach successfully resolves the narrow Raman rotational transition S0(0) of H2 with sub‐kHz spectral resolution and attains an unprecedented sensitivity of 0.5 ppm using ...

Coexistence of continuous variable QKD with intense DWDM classical channels
, 2015 We demonstrate experimentally the feasibility of continuous variable quantum key distribution (CV-QKD) in dense-wavelength-division multiplexing networks (DWDM), where QKD will typically have to coexist with several co- propagating (forward or backward ...

The Review of Laser Engineering, 1999 An alternating dispersion scheme for dispersion managed WDM soliton is proposed over standard fiber line to improve the tolerance of path-average dispersion of the fiber combination. A WDM transmission experiment at 4×20 Gbit/s over 1000 km was successfully demonstrated with the proposed dispersion arrangement.
