Ultra-Stable Silicon Cavities for Fundamental Researches and Applications

摘要

We report on preliminary results of frequency instability of two laser systems stabilized by perspective cryogenic monocrystalline silicon cavities. The obtained value of 5 × 10~(-15) exceeds the thermal noise floor by more than an order of magnitude. The most likely reason is residual amplitude modulation fluctuations in the electro-optical scheme.
