中文摘要：

利用平面对称碰撞和＂原位＂测量实验方法,对Z-切石英的弹性响应特性和窗口光学特性进行了研究.结果表明,在至少10GPa内,Z-切石英为弹性单波响应,且透光性良好,可作为速度剖面测试系统的光学窗口.10GPa内Z-切石英的冲击波速度和粒子速度之间满足线性关系.1550nm入射光条件下,其窗口速度修正采用指数形式较为精确,线性修正仅适用于特定范围;而折射率随密度的变化关系则可采用线性函数进行较好描述.以上结果为Z-切石英应用于基于1550nm光源激光干涉测速系统的光学窗口提供了依据.

英文摘要：

The elastic properties and optic characteristics of shocked Z-cut quartz were carefully examined,by using symmetric plate impact and in situ measurement.Results show that Z-cut quartz exhibits a simple-wave elastic response and keeps transparent up to a pressure of no less than 10 GPa,and it can be used as the opical window for velocity measurement within this pressure range.The relation of elastic shock wave velocity and particle velocity satisfies linear function very well.On the other hand,the velocity correction of Z-cut quartz at incident laser wavelength of 1550 nm can be better represented by exponential function than linear one,while the relation between refractive index and density of Z-cut quartz at 1550 nm satisfies the linear function very well.The results in this paper lay a foundation for using Z-cut quartz as optical windows of interferometer systems working with laser at 1550 nm wavelength.
