Abstract
An infrared non-linear optical crystal has the following molecular formula: AXYM, in which A is Ba, Sr or Pb; X is Zn, Cd or Mn; Y is Ga, In or Al; and M is S, Se or Te. The crystal belongs to trigonal system and has space group R3. The crystal BaZnGaSis a type I phase matching non-linear optical material, in a particle size range of 150˜210 μm, its powder frequency doubling intensity and the laser damage threshold are respectively 0.5 times and 28 times those of the commercial material AgGaS. Other crystals have the same or similar structure and properties such as optical property. The infrared non-linear optical crystal of the present application has important prospects in military and civilian applications, and can be used in electro-optical countermeasures, resource detection, space antimissile and communications, etc.
