我们报告了一种在空气中提供亚微米分辨率的位移计量装置。该装置基于法布里-珀罗腔。然而，与当前基于法布里-珀罗腔的位移装置不同，我们采用了一种新颖的基于飞秒激光的任意波长合成器，它可以有效抑制大气扰动，同时提供非常广泛且精确的输出波长调谐。波长合成器提供低于 10 阿米的波长分辨率。该装置提供亚下午长度稳定性，积分时间长达一分钟，亚十下午长度稳定性长达半小时，无需对法布里-珀罗腔进行气密封闭。 (c) 2006 年美国光学学会。
We report on a displacement metrology setup that provides sub-pm resolution in air. The setup is based on a Fabry-Perot cavity. However, unlike current Fabry-Perot cavity based displacement setups we incorporate a novel fs-laser based arbitrary wavelength synthesizer that provides efficient suppression of atmospheric disturbances while providing very wide and precise tuning of the output wavelength. The wavelength synthesizer provides sub-10 attometer wavelength resolution. The setup provides sub-pm length stability for integration times of up to one minute and sub-10 pm for up to half an hour without airtight enclosure of the Fabry-Perot cavities.
