Abstract :
We present the design of two different geometries of optical cavities (vertically and horizontally mounted). The Finite Element Modeling analysis is used to predict and decrease the influence of vibrations on the cavity stabilized lasers. Inspired by the results of simulation, two cavities have been constructed. Vibration sensitivity coefficients measured are equal or better than 1.4x10-11/(m.s-2) for all spatial directions. A preliminary measurement of the two independent cavity stabilized lasers shows a relative frequency stability of about 10-15 @ 1s.
