摘要
采用５～６Ｎ的高纯Ａｇ，Ｇａ，Ｓｅ单质按ＡｇＧａＳｅ２的化学配比配料，在１１００℃下合成了单相的ＡｇＧａＳｅ２多晶原料．用改进的布里奇曼法生长出２２ｍｍ×７０ｍｍ的ＡｇＧａＳｅ２单晶体，并对其品质进行了研究．结果表明：生长的晶体完整性好，具有较高的光学质量，用于对１０．６μｍ的ＣＯ２激光倍频，获得了８．
Dense single phase AgGaSe 2 polycrystal matlrials has been synthesized successfully at 1100℃,by 5～6N′ high pure Ag,Ga,Se elements,according to stoichiometric ratio of the AgGaSe 2.Single crystal of the AgGaSe 2 with 22mm in diamenter and 70mm in length suitable for IR applications is obtained using modified Bridgman technique.The qualities of the crystal have been studied.The results show that the qualities of the crystal are high.When the crystal is used for second harmonic generation of 10.6μm CO 2 pulsed laser output,8.2% harmonic energy conversion efficiency was obtained
