According to a simple calculation model, both the power spectrum formula and the coherent harmonic radiation formula are derived. With these formulae, the coherent harmonic radiation of asymmetrical optical klystron configuration is discussed. For the storage ring coherent harmonic FEL in Hefei, a method of the coherent harmonic radiation of asymmetrical optical klystron configuration is investigated, and the detailed calculation results are given. Thus adjusting the parameters of optical klystron and outer laser makes the resonant wavelength of radiation section to equal to the second harmonic wavelength of outer laser, and the coherent strengthen factor 10 9 can be acquired.
