Abstract
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 inequilateral triangle prism, or are different triangle prisms. It is hopeful to obtain frequency 6th harmonic output.
Claims8
A prism-nonlinear optical crystal coupler for laser frequency conversion, wherein M pieces of nonlinear optical crystal are included in the coupler, where M is an integer greater than or equal to 1, the incident surface and the exit surface of the nonlinear optical crystal are plane, a coupling prism is provided on the incident surface or/and the exit surface of the nonlinear optical crystal.
