Description

technical field [0001] The present invention relates to a K 4 (HC 3 N 3 S 3 ) 2 ·H 2 O compound, K 4 (HC 3 N 3 S 3 ) 2 ·H 2 O crystal preparation method and K 4 (HC 3 N 3 S 3 ) 2 ·H 2 O crystals are used to make optical devices. [0002] technical background [0003] Nonlinear optics, i.e. double frequency response (SHG), and linear optical properties, i.e. birefringence (Δn), are two important optical properties that are widely used. The nonlinear optical effect refers to the phenomenon that when a laser beam passes through a nonlinear optical crystal, the frequency of the beam will change. It can be used in medical treatment, information storage, precision micro-manufacturing and other fields. Birefringence refers to the phenomenon that a beam of light is projected onto the surface of a crystal to produce two beams of refracted light. It can be applied to flat panel display, medical diagnosis, optical fiber communication and other fields. Since these two ...
