We present an ultra-stable laser based on a compact Fabry-Perot cavity with a thermal noise limit expected at 2 × 10 15 in trems of fractional frequency stability. The 25 mm long cavity is housed in a cubic vacuum chamber with a volume of about 2.2 L. The measured phase noise is 3 dBrad2/Hz at 1 Hz with a simple optical set-up at 1542 nm.
We present the development of an ultra-stable laser based on a Fabry-Perot cavity made from single crystal silicon. This cavity is cooled down to 17 K to reach a nulling of the thermal expansion. Thanks to the high mechanical quality factor of silicon and to the low temperature, the expected thermal noise limited fractional frequency instability is 3 × 10−17.
