We study the intensity and phase noise as well as the spectral broadening of narrowband single-frequency fiber laser emission after amplification in a polarization-maintaining Raman fiber amplifier. The optical properties of a 10-W 1266-nm single-fre

Deploying fibre cables to offshore installations may desire a pluggable construction for sub-sea use. Sub-sea connection of fibre cables, carrying high power Raman pump power, using a wet-mate connector is demonstrated for the first time.

We report a 100-W continuous-wave (CW) 1178-nm narrowband polarization-maintaining (PM) Raman fiber amplifier (RFA) based on ESO’s patented RFA technology. A linearly-polarized 15-mW narrow-linewidth 1178-nm seed laser was amplified in a two-stage

The performance of large ground-based optical telescopes is limited due to wavefront distortions induced by atmospheric turbulence. Adaptive optics systems using natural guide stars with sufficient brightness provide a practical way for correcting th

An all-fiber 1.48 µm generator based on a LD-pumped Yb-doped double-clad laser and cascaded Raman wavelength converter has been developed. Second-order Raman Stokes radiation was generated in a phosphosilicate-fiber resonator formed by two pairs of

Large telescopes equipped with adaptive optics require 20-25W CW 589-nm sources with emission linewidths of ~5 MHz. These Guide Star (GS) lasers should also be highly reliable and simple to operate and maintain for many years at the top of a mountain
