In this article, we present our analysis of the Raman-induced wavelength shift (RIWS) in configuring high-performance temperature sensor by employing a highly nonlinear Chalcogenide (As30S70) microstructured optical fiber (MOF) having central holes partially filled with Chloroform (CHCl3). Through ...
RAMAN Raman Shift Cell The Raman Shift Cell is designed to convert visible or deep-red pulses generated by a dye laser to the near infrared (900 .. 1500 nm) wavelength range. Wavelength conversion is achieved by the Raman effect, i. e. Stokes-shift in a gas cell filled with either ...
These techniques include raman scattering , in which light returns with a shift in wavelength as a result of atomic or molecular laser excitation . 这项技术包含拉曼散射,这种散射指反射光会因为原子或分子的激发而有一个波长上的移动。 The resolving power of a telescope is determined by the ratio of...
(1997). The device consists of a GaAs-based DBR, i.e., wafer bonded to InP-based active layers, with a micromachined tunable top dielectric DBR mirror to produce the wavelength shift. A tuning range of 75 nm has been achieved for a voltage of 50 V, which is relatively high. Another ...

The combination of flexibility and intrinsic efficiency of this approach is unmatched by alternatives that use multiple neodymium lines or optical parametric generation. The typical Stokes shift of most solid-state Raman materials — 700 to 1000 cm–1— allows the generation of up to five or six ...

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 ...
Note, however, that this wavelength falls in the S-band and may also overlap with Raman pumps for the L-band. Yet another choice used by some vendors is the 1620 nm wavelength, on the outer edge of the L-band. This choice avoids most of the problems above, except that we have to ...
61 demonstrated that the Raman contribution manifests itself in exactly the same way (through a considerable red-shift of the laser spectrum) for all near-infrared and mid-infrared laser pulses. We also mention the experiments by Pigeon et al.66,67, where the total nonlinear index of air n2...
