We report what is believed to be the first demonstration of laser frequency stabilization directly to persistent spectral holes in a solid-state material. The frequency reference material was deuterated CaF(2): Tm(3+) prepared with 25-MHz-wide persistent spectral holes on the H(6)(3)?H(4)(3) transition at 798 nm. The beat frequency between two lasers that were independently locked to persistent spectral holes in separate crystal samples showed typical root Allan variances of 780+/-120Hz for 20-50-ms integration times.
我们报道了据信是首次直接将激光频率稳定到固态材料中的持久光谱孔上的演示。频率参考材料是氘化CaF₂: Tm³⁺，在798 nm处的H₆³→H₄³跃迁上制备了宽度为25 MHz的持久光谱孔。独立锁定到不同晶体样品中持久光谱孔的两台激光器之间的拍频，在20 - 50毫秒积分时间内显示出典型的均方根阿伦方差为780±120Hz。
