Abstract
A nonlinear optical system may include optics, a non-linear optical crystal, and a uni-axial focusing element. The non-linear optical crystal is configured to generate an output beam from a non-linear optical interaction with an input beam. The optics are configured to image the input beam to an original input beam waist within the non-linear optical crystal, whereby the output beam has an original output beam waist. The uni-axial focusing element is optically coupled to the non-linear optical crystal. The uni-axial focusing element is configured so that the output beam has a new output beam waist at approximately the same location as the original output beam waist.
