The team led by Professor Chen Jingbiao from the School of Electronics Engineering at Peking University has attained a groundbreaking advancement in the realm of quantum mode-locked Faraday lasers. For the first time, they have successfully demonstrated mode-locked operation of Faraday lasers, employing an atomic optical filter as a saturable absorber. The resulting laser pulse spectrum precisely encompasses the quantum transition frequency of atoms, while the repetition frequency can be tuned via the Faraday slow light effect. This unique capability presents extensive application potential in the field of high-precision atomic multi-frequency spectroscopy technology. The research findings have been published in Applied Physics Letters.
