Axions and axionlike particles are strongly motivated dark-matter candidates that are the subject of many current ground based dark-matter searches. We present first results from the Axion Dark-Matter Birefringent Cavity (ADBC) experiment, which is an optical bow-tie cavity probing the axion-induced birefringence of electromagnetic waves. Our experiment is the first optical axion detector that is tunable and quantum noise limited, making it sensitive to a wide range of axion masses. We have iteratively probed the axion mass ranges 40.9-43.3 neV/c^{2}, 49.3-50.6 neV/c^{2}, and 54.4-56.7 neV/c^{2}, and found no dark-matter signal. On average, we constrain the axionlike particle and photon coupling at the level g_{aγγ}≤1.9×10^{-8} GeV^{-1}. We also present prospects for future axion dark-matter detection experiments using optical cavities.
轴子和类轴子粒子是备受关注的暗物质候选者，是当前许多地面暗物质搜索的对象。我们展示了轴子暗物质双折射腔（ADBC）实验的首批结果，该实验是一个光学领结腔，用于探测轴子引起的电磁波双折射。我们的实验是首个可调谐且受量子噪声限制的光学轴子探测器，使其对广泛的轴子质量敏感。我们已反复探测了轴子质量范围40.9 - 43.3 neV/c²、49.3 - 50.6 neV/c²和54.4 - 56.7 neV/c²，未发现暗物质信号。平均而言，我们将类轴子粒子与光子的耦合限制在g_{aγγ}≤1.9×10^{-8} GeV^{-1}的水平。我们还展示了未来使用光学腔进行轴子暗物质探测实验的前景。
