Abstract
A light conversion module includes a coupler for combining two light beams to form a combined light beam, a nonlinear crystal arranged to receive the combined light beam and configured to include a plurality of poling regions for performing successive nonlinear frequency mixing processes, a first optical device configured to focus the combined light beam onto the nonlinear crystal, a first moving stage carrying the nonlinear crystal and moving the nonlinear crystal for an adjustment of a focus position of the combined light beam on the nonlinear crystal, and an optical detector configured for measuring a power level of the light beam from the nonlinear crystal for the adjustment of the focus position of the combined light beam on the nonlinear crystal.
