【 摘 要 】

This article presents the design and the conception of an ultra-compact Fabry-Pérot cavity which will be used to develop an ultra-stable laser. The proposed cavity is composed of a 25 mm long ULE spacer with fused silica mirrors. It leads to an expected fractional frequency stability of 1.5 × 10-15limited by the thermal noise. The chosen geometry leads to an acceleration relative sensitivity below 10-12/(m/s2) for all directions.
