摘要：

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