  Axions and axion-like 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
range 40.9-43.3$\text{ neV/c}^2$, 49.3-50.6$\text{ neV/c}^2$, and
54.4-56.7$\text{ neV/c}^2$, and found no dark matter signal. On average, we
constrain the ALP-photon coupling at the level $g_{a\gamma\gamma} \leq
1.9\times 10^{-8} \text{ GeV}^{-1}$. We also present prospects for future axion
dark matter detection experiments using optical cavities.
