| titleOfInvention | A kind of C20H18N2O2Nonlinear optical crystal and its preparation method and purposes |
| abstract | A kind of C 20 H 18 N 2 O 2 Nonlinear optical crystal and preparation method and purposes, the crystal do not have symmetrical centre, belong to rhombic system, space group is Pna21, and cell parameter is： α=β=γ=90 °, Z=4, Can be lived seed-grain method growth using spontaneous crystallization volatility process, spontaneous crystallization falling temperature method；Large-size high-quality crystal is grown with fast growth, the low feature of cost, and easily；Gained C 20 H 18 N 2 O 2 Crystal has larger nonlinear optical effect, and powder SHG effect intensity is 2~3 times of OH1, and chemical property is stable, not deliquescence, the need for being adapted to infrared band laser frequency conversion, its can be used to make device for non-linear optical, comprising at least a branch of incidence electromagnetic radiation is passed through at least one piece C 20 H 18 N 2 O 2 Device of at least a branch of frequency different from the output radiation of incidence electromagnetic radiation is produced after nonlinear optical crystal. |
