In order to study property of polyvinyl alcohol films doped with methlyene blue under low power continuous-wave laser radiation generated by He-Ne laser,degenerate four-wave mixing(DFWM) was used to study relations of phase-conjugate(PC) signal along with incidence time,forward-pump beams and backward-pump beam.The PC signal influence from induced holographic transmission and reflection gratings were studied.We observed a maximum PC reflectivity of 0.27% in these dye-doped polyvinyl alcohol films.The result of research is helpful in nonlinear effect study in dye-doped solid.
