Stimulated Raman scattering (SRS) is one of most efficient methods for generating new laser lines. In recent years, SRS in crystalline Raman media have attracted much attention for the advantages of high Raman scattering gain, favorable thermal conductivity and good mechanical and chemical stability [1-3]. So far most crystalline Raman lasers focus on Stokes generation. In contrast to Stokes generation,...
This paper introduces a fast heuristic resource provisioning algorithm for dynamic wavelength services on agile reconfigurable ROADM networks on which customer connections are only constrained by access ports.
We have demonstrated an intense plasma-based THz source using ~5 TW femtosecond laser pulses to irradiate solid targets. The energy of a single THz pulse emitted in the laser specular direction increases with the laser energy. The maximum THz energy can be as high as tens μJ/sr. The polarization of the THz pulse is measured to be linear.
A silicon waveguide based splitter is a key device for polarization diversity circuit. A bilayer waveguide structure was proposed by MIT to split the input light into its orthogonal components. It is challenging to fabricate a bilayer silicon waveguide by the conventional two-step-etching process due to precise alignment and accurate etch thickness required. In addition, the partial etched waveguide...
In an actively Q-switched intracavity Raman laser with a b-cut KLuW crystal as the Raman medium and an Nd:YAG crystal as the gain medium, we got the first to ninth order Stokes wavelengths for the 88 cm-1 Raman shift. The wavelengths included 1074 nm, 1085 nm, 1095 nm, 1105 nm, 1117 nm, 1128 nm, 1140 nm, 1151 nm and 1163 nm.
