Abstract

The invention provides a DKDP crystal blank dynamic extinction ratio testing device. The device comprises a base. A rotating disk, a polarization mechanism, an electrode mechanism and a detector mechanism are arranged on the base. A reflection mechanism is arranged at the bottom of the base. A polarizer mechanism and a polarization analyzer mechanism are arranged on the rotating disk. The polarization mechanism, the polarizer mechanism, the electrode mechanism, the polarization analyzer mechanism and the reflection mechanism are arranged in order from top to bottom. The detection mechanism is arranged on one side of the reflection mechanism. The device has no limit on the size of a crystal to be detected and has a quick test speed. Electrodes are loaded onto the crystal through conductive rubber, so that the electrodes can be easily loaded without damaging the surface of the crystal. By moving the crystal, test parameters of the crystal at any position can be tested, thereby providing a basis for crystal selection.

Description

technical field [0001] The invention relates to a method and a device for testing the dynamic extinction ratio of DKDP crystal blanks, and belongs to the technical field of dynamic extinction ratio testing of DKDP crystal blanks. Background technique [0002] Dynamic extinction ratio is an important indicator of DKDP electro-optic crystals. Its measurement needs to be completed by adding electrodes to the DKDP crystal. It cannot be realized when the DKDP crystal is in the rough state. Only the DKDP crystal is processed into a finished product or has been formed. It can only be detected when the semi-finished product is used, so when selecting the DKDP crystal blank, it is impossible to identify the quality of the crystal through the dynamic extinction ratio. [0003] Conventional DKDP crystal dynamic extinction ratio test, such as figure 1 As shown, the beam emitted by the laser becomes linearly polarized light through the polarizer, passes through the DKDP electro-optic cr...
