研究了不同掺杂浓度的GeO2、P2O5、F、TiO2Al2O3、B2O3型掺杂二氧化硅玻璃的声学特性。用225 MHz线聚焦束扫描声学显微镜进行定量测量。给出了不同掺杂浓度对声速的影响。结果表明，与纯熔融二氧化硅相比，Al_2O_3掺杂剂的声速增大，而其他掺杂剂的声速减小。我们还发现，对于给定的掺杂浓度，声速的分数变化大于折射率的分数变化。
Acoustic characterization of doped silica glasses with a GeO2, P2O5, F, TiO2, Al2O3, or B2O3 dopant having different concentrations is presented. Quantitative measurements were performed with a 225-MHz line-focus-beam scanning acoustic microscope. The acoustic velocity variation due to different dopant concentrations is given. It has been found that the Al2O3 dopant increases, but the other dopants decrease, the acoustic velocity as compared with that of the pure fused silica. We have also found that the fractional change in acoustic velocity is greater than that in refractive index for a given dopant concentration.
