Abstract

We present experimental results of the frequency stabilization of a Nd:YAG laser at 946 nm to the Hertz-level. The laser will be used for ultra-high resolution spectroscopy of the 5s²¹S₀-5s5p³P₀ transition at 237 nm in In⁺ (natural linewidth 0.82 Hz) and will ultimately serve as a local oscillator of an optical frequency standard based on a single traped Indium ion. The frequency stability of the laser is obtained by locking it onto an external reference cavity of high finesse, placed on an active vibration isolation platform.
