化学气相沉积硒化锌
cvd zinc selenide
硒化锌材料是一种黄色透明的多晶材料,结晶颗粒大小约为70μm,透光范围0.5-15μm。由化学气相沉积
(cvd)方法合成的硒化锌材料基本不存在杂质吸收,散射损失极低。由于对10.6μm 波长光的吸收很小,
对热冲击具有很高的承受能力,使它成为高功率co2 激光器系统中的最佳光学材料。此外在其整个透光波
范围内,也广泛用于不同光学系统中。
zinc selenide is a clear yellow polycrystallinematerial with a grain size of approximately 70
µm,transmitting in the range0.5-15µm.it is essentially free of extrinsic impurity absorptions,
providing extremely low bulk losses from scatter.zincselenide, produced by the method of
chemical vapour deposition, is the preferred material foroptics used in high power co2 laser
systems due to its low absorptionand high resistance to thermal shock making at 10.6µm.
however it is also a popular choice in systems operating at various bands within
its widetransmission range.
