A project for a new alkali vapour magnetometer, optically pumped by a diode laser
Main Article Content
Abstract
We present here a project for the industrial development of a new magnetometer that is intended to achieve the highest performance in measuring geomagnetic field. The instrument is based on the well-known technology of optically pumped alkali vapour magnetometers. Unlike current commercial models, a diode laser replaces the traditional radio-frequency lamp as pumping source and our magnetometer uses potassium as reference atom, contrary to the more traditional cesium or rubidium. The advantages of this choice are discussed. Preliminary experimental results on a prototype show an expected accuracy better than 1 pT/Hz-1/2.
