超抛光楔形硼硅酸盐纳米电池的制备与表征
Fabrication and characterization of super-polished wedged borosilicate nano-cells
摘要:
我们报道了一种厚度在0 ~ 1 μm之间线性变化的全玻璃蒸气室的制作。该电池由Borofloat玻璃制成,具有超级抛光粗糙度,全光学粘合组装和易于填充碱蒸汽。我们详细介绍了具有挑战性的制造步骤,并提出了实验光谱所产生的离轴荧光和透射光谱的铯D1线。非常小的表面粗糙度为1埃rms,有望研究原子-表面相互作用或最大限度地减少寄生杂散光。
英文摘要:
We report on the fabrication of an all-glass vapor cell with a thickness varying linearly between (exactly) 0 and ~ 1 μm. The cell is made in Borofloat glass that allows super polish roughness, a full optical bonding assembling and easy filling with alkali vapors. We detail the challenging manufacture steps and present experimental spectra resulting from off-axis fluorescence and transmission spectroscopy of the Cesium D1 line. The very small surface roughness of 1 Angström rms is promising to investigate the atom-surface interaction or to minimize parasite stray light.
