Description
Technical field
The invention belongs to nonlinear optical material and synthetic.
Background technology
Non-linear optic crystal has frequency-doubled effect (SHG), and selling off the high-tech areas such as information processing at laser frequency conversion, Electro-optical Modulation, light has significant application value.Non-linear optic crystal has obtained paying close attention to widely with its good character.Nonlinear optical material is in modern science and technology, particularly in some military and civilian high-tech areas, such as the communication of submarine deep water, blinding laser weapons, the ocean locating fish, video disc recording, color laser printing, laser projection tv, photometry calculation and optical-fibre communications etc. has a series of important application.The non-linear optic crystal of at present practical application comprises KH
