Abstract

We exploit femtosecond laser writing to create an alkali-metal vapor cell, the core component of an atomic sensor. This laser-written vapor-cell (LWVC) technology allows arbitrarily-shaped 3D geometries and holds the potential for integration with photonic structures and optical components. The fabrication steps of a vapor cell in silica glass will be shown and the possibility of its integration with GRN lenses, as an example of miniaturized optical component, will be investigated. We successfully use this device for sub-Doppler saturated absorption spectroscopy and single beam optical magnetometry to validate its functioning.
