Compact light control unit for use in a low-SWaP strontium optical atomic clock

Using FBH’s unique hybrid micro-integration technology, we realized a compact light control unit for laser beam conditioning in a transportable strontium-based optical atomic clock. Equipped with miniature acousto-optic and electro-optic modulators, the all-fiber coupled module enables amplitude and phase modulation of an optical field provided by an external 461 nm laser source.
