Abstract: Raman spectrum of CCl4 is enhanced by factor of 102~103 by means of hollow core quartz optical fiber fills up with the CCl4 solution.The experimental results show that the concentration of the solution effects not only the intensity(scattering factor) of some Raman spectrum lines,but also the numerical aperture of the liquidcore fiber.There is a optimal concentration at which the maximum Raman spectrum can be obtain.
