标题： Highly stable piezoelectrically tunable optical cavities

摘要： 我们利用集成压电作动器的高精细光学腔，实现了高度稳定且可调谐的频率参考。作为压电材料，我们使用了陶瓷PZT、石英晶体或PZN-PT单晶。锁定到这些腔体上的激光器表现出优于1 × 10^{-14}的相对频率稳定性，这种稳定性很可能不受压电作动器的限制。压电腔体可以通过电调谐超过一个自由光谱范围（> 1.5 GHz），并且频率稳定性仅有轻微下降。此外，我们提出了一种新型腔体设计，其中压电作动器被预应力安装在腔体间隔组件之间。此设计具有密封的腔内体积，适合用于例如腔增强光谱学等领域。 显示英文摘要

摘要： We have implemented highly stable and tunable frequency references using optical high finesse cavities which incorporate a piezo actuator. As piezo material we used ceramic PZT, crystalline quartz, or PZN-PT single crystals. Lasers locked to these cavities show a relative frequency stability better than 1 x 10^{-14}, which is most likely not limited by the piezo actuators. The piezo cavities can be electrically tuned over more than one free spectral range (> 1.5 GHz) with only a minor decrease in frequency stability. Furthermore, we present a novel cavity design, where the piezo actuator is prestressed between the cavity spacer components. This design features a hermetically sealable intra cavity volume suitable for, e.g., cavity enhanced spectroscopy.
