光纤材料色散引起的相位失配的研究

his paper studies the four-wave mixing effect, draw the relatinship of pump frequency and four-wave mixing effect of phase mismatch, Through the experiment results we can get the influence of pump frequency to conversion power， the relationship of difference between pump frequency and transform through theoretical derivation, For the wavelength of light wavelengths network to solve the problem of an offer.we can get the phase mismatch formula near zero dispersion wavelengths in dispersion material, using optical optisystem simulation software simulation, and maple software draw pump frequency and phase mismatch relationship curves.
