When the waves are moving away from the light beam, the largest signal is observed in retroreflection and the Stokes shift moves to longer wavelengths, as in stimulated Raman scattering. When the acoustic waves are moving toward the light beam, their frequency will add to the frequency of the laser beam and the scattered light will have a frequency increased by the acoustic wave frequency.

Due to the presence of stimulated Raman Scattering (SRS) in the HNLF, it is possible that the optimal power distribution between the pumps may be obtained when their power is not equal.
The system was found to emit stimulated Raman scattering (SRS) signals when irradiated by the laser light and which corresponded to 2957 cm-1 Raman mode of s (C-H) of O-CH3 with s (C-H) of a-CH3 and a (CH2).
The evolution of the input signal power of ith channel in DWDM system [P.sub.si] and the input pump power [P.sub.p] propagating along the single-mode optical fiber in milliwatt, can be expressed by the following different equations called propagation equations that include pump-to-pump, signal-to-signal and pump-to-signal Raman interactions, spontaneous Raman emission and its temperature dependency, stimulated Raman scattering, pump depletions due to Raman energy transfer, high-order stokes generation, multiple Rayleigh backscattering, fiber loss and spontaneous emission noise can be expressed by the following equations (1, 2, 3) [5-9].
Micro/nanofibers, as one of the most important integrated photonic devices, are used as sensors [7-10], production of stimulated Raman scattering [11], low-threshold supercontinuum generation [12], nanowire lasers [13], low-loss light transmission medium [14], and so on.
Compared with the supercontinuum generation in silica fibers, the effect of stimulated Raman scattering in silicon waveguide plays a minor role.
Several nonlinear effects, such as stimulated Raman scattering (SRS), four-wave mixing (FWM), soliton fission, and dispersive waves (DWs) have been demonstrated to generate the narrowband spectral components for the pump and Stokes beams through adjusting the location of the excitation wavelength relative to the zero-dispersion wavelength of PCFs.
With the breakthrough using stimulated Raman scattering microscopy, fluorescent markers are unnecessary.
Different nonlinear effects include, Stimulated Raman Scattering (SRS), Four Wave Mixing (FWM), Self Phase Modulation (SPM), cross phase modulation (XPM), Stimulated Brillouin Scattering (SBS) and Carrier Induced Phase Modulation.
