946-nm Nd:YAG digital-locked laser at $1.1\times 10^{-16}$ in 1 s and transfer-locked to a cryogenic silicon cavity

A. Didier, S. Ignatovich, E. Benkler +2

We present a Nd:YAG ultra-stable laser system operating at 946 nm and demonstrate a fractional frequency instability of $1.1\times 10^{-16}$ at 1 s by pre-stabilizing it to a 30 cm-…
