Wavelength tuningIn addition to the well-known problem related to the growing demands in telecom fiber optical data transmission lines with extended bandwidth in recent years the researchers developed an interest in mode-locked fiber lasers of 1600-1700 nm spectral region in a number of biomedical ...
We investigate the dependence of output pulse width, wavelength shift, and conversion efficiency of Raman soliton formation on several input parameters. A femtosecond Raman soliton source with its wavelength tunable from 1500 to 3600 nm can be obtained. It is found that the maximum conversion ...

In this paper, we demonstrate multi-wavelength Raman lasing in an X-cut high-QLN microresonator with Raman frequency shifts of 250 cm−1, 628 cm−1, and 875 cm−1via pumping with the transverse electric (TE) polarisation and a shift of 238 cm−1with the traverse magnetic ...
b Transmission spectra as coupled to the substrate with (colored) and without (grayed) nanoantennas. The distances \({d}\) from top to bottom are 536 nm, 332 nm, 230 nm, 128 nm, and 26 nm, respectively. c Resonance shift and linewidth broadening of the hybrid mode as the...
signature from a material. The interrogating light (a?? single wavelength) interacts with the chemical bonds in?? the material causing an energy shift depending on the?? type of bond. These shifts show up as peaks in a?? Raman spectrum. The spectrum is unique to a?? material (glass, po...
a Raman spectrum that does not interfere with that of your analyte. Penetration depth in 3D images is limited by the optical properties of your sample. If your sample does not transmit the 633nm laser light well, you can expect a dramatic fall-off in signal intensity as you attempt to ...
