Embodiment Construction

[0030] The method of the present invention will be further described in the form of embodiments in conjunction with the accompanying drawings.

[0031] In this example, the infrared nonlinear OPO optical element is prepared with chalcopyrite negative uniaxial crystal AGIS, and its phase matching angle θm=56.0°, azimuth angle .

[0032] The cleavage planes {112} and {101} are obtained through the presence of semi-open holes with uniform reflection on the surface of the AGIS crystal ingot.

[0033] In this embodiment, the steps of directional cutting are as follows:

[0034] (1) Determine the C-axis direction of the crystal

[0035] Such as figure 1 As shown, the known cleavage plane (112) of the AGIS crystal is placed at the origin position on the standard pole figure of the (112) plane of the said crystal with Wu’s grid scale, and then the crystal is rotated to place the other cleavage plane The normal direction of {101} is aligned with any pole in {101} on the standard p...

Abstract

The invention relates to a directional cutting method for preparing infrared nonlinear optical elements from a chalcopyrite uniaxial negative crystal, which comprises the following steps: (1) according to cleavage surfaces {112} and {101} of the chalcopyrite uniaxial negative crystal, utilizing a crystal standard pole figure with Wuwov's intersection ruler and an X-ray diffractometer to determine the direction of a C axis of the crystal through theta-2theta continuous scanning; (2) putting the crystal of which the direction of the C axis is determined on a cutting machine, rotating a sample stage for delta theta far away from the direction of the C axis according to a phase matching angle theta m required by an optical element, and cutting the crystal to obtain an original sample of the optical element, wherein the delta theta= theta m - theta (112); (3) putting the original sample of the optical element on the sample stage of the X-ray diffractometer, determining an oscillation photograph of a cutting surface of the original sample of the optical element, and obtaining a diffraction peak place value theta' and delta theta', wherein the delta theta'=absolute (theta'- theta'(112)); and (4) finishing the optical element, and correcting the cutting surface of the original sample of the optical element until the delta theta'=the delta theta.

Description

technical field [0001] The invention belongs to the field of preparation and processing of crystal nonlinear optical components, in particular to a directional cutting processing method for preparing infrared nonlinear optical components with chalcopyrite negative uniaxial crystals without direction characteristics. Background technique [0002] Chalcopyrite crystals used as infrared nonlinear optical components mainly include I-III-VI compounds and II-IV-V compounds. The chalcopyrite single crystals include positive uniaxial crystals and negative single crystals. Axial crystals are generally prepared by the Bridgman-Stockbarger method (B-S method). Due to the strong constraints of the growth container, coupled with the influence of growth rate, melt viscosity, etc., the grown ingot is usually cylindrical, with no obvious directional characteristics in appearance. To accurately process it into various phase matching angles (θm) and azimuth angles ( ), such as frequency do...
