Abstract
The investigations on the multi-cascade processes of four-wave mixing (FWM) in liquid cored optical fiber is reported. The core material is ethylbenzene and the wavelength of its first order. Stokes is 562 nm by the pumping light of 532 nm. The dye laser is tunable and so are its FWMs. The frequencies of FWMs and their cascade FWM among the frequency difference of the first order Stokes line and the dye laser, (omega) 1s - (omega) d, and the dye laser; or it and the second order Stokes line; or it and the third order Stokes line; or it and the pumping light are (omega) d -((omega) 1s - (omega) d), (omega) d -2((omega) 1s - (omega) d), and (omega) d -3((omega) 1s - (omega) d); or (omega) 2s - ((omega) 1s - (omega) d) and (omega) 2s - 2((omega) 1s - (omega) d); or (omega) 3s - ((omega) 1s - (omega) d) and (omega) 3s - 2((omega) 1s - (omega) d); or (omega) p -((omega) 1s - (omega) d), (omega) p -2((omega) 1s - (omega) d), and (omega) p -3((omega) 1s - (omega) d), respectively. In the output of liquid cored optical fiber there are Stokes lines, the broadening of each line, the dye laser, the pumping light, the FWMs and their cascade FWMs. We point out that the FWM process is not only to initiate those obtained FWMs and their cascades, but also to contribute to the stimulated Raman scattering and the stimulated Rayleigh wing scattering for generating higher orders of Stokes and anti-Stokes line and for expanding the spectrum widely in the red-shifted broadening and the blue-shifted broadening in liquid cored optical fiber.
