The present invention relates to prism-nonlinear optical crystal couplers for frequency conversion, including M pieces of nonlinear optical crystal and one coupling prism stuck to the incident surface or/and exit surface of the crystal by optical stick or a matching liquid. The coupling prisms are the same triangle prisms of right triangle prism, equilateral triangle prism, or inequlateral triangle prism, or are different triangle prisms. It is hopeful to obtain frequency 6th harmonic output.
