ABSTRACT:
The invention relates to a non-linear optical material comprising a salt of an organic compound with an optically active organic acid, wherein said organic compound has a conjugated .pi. electron system containing both electron donor and acceptor groups and has at least one substituent group represented by the following formulas (1), (2) and (3) which is located outside of said conjugated .pi. electron system. The invention also concerns a method of manufacturing the optical material and an optical converter which uses the non-linear optical material. ##STR1## According to the invention, a second-order non-linear optical material, which is readily capable of crystal growth, permits a large crystal to be readily obtained, and ensures high hardness of the crystal and gives excellent processibility and non-linear optical characteristics.
