Diagram of the experimental apparatus used for magnetic-field detection. λ/2 is a half-wave plate, λ/4 is a quarter-wave plate, PBS is a polarizating beam splitter, FC is a fiber-optic coupler, λM is a wavelength meter, Rb is a rubidium vapor cell, D is a diaphragm, P is a polarizer, M is a mirror, A is an inlet of hot air used for cell heating, WP is a Wollaston prism, DPD is a differential photodiode, PC is a computer, DAVLL is a dichroic atomic vapor laser lock system, B is a static field for the DAVLL system, BAC is an oscillating field and B0 is a static field used for magnetometric purposes. Directions of magnetic fields are marked by bright blue arrows.
