Abstract
Recently, a distributed Bragg reflector (DBR) laser diode was develope d by Spectra Diode Labs for helium optical pumping experiments. An int eresting feature is the possibility of frequency modulation of the dio de output by modulating the current intensity leading to a new pumping scheme, never reported before. An application to the realisation of v ery simple earth magnetometers without external modulators or external RF field is proposed.
