    Researchers Demystify Contradiction of Supermode Microcavity Lasers

    Article obtained from Photonics RSS Feed.

    Stimulated scattering in supermode microcavities, such as Raman or Brillouin lasers, has proven useful for precision measurements by exploiting the beat note in their lasing spectra. The existence of the beat note (which corresponds to the energy splitting of supermodes) presents a question that researchers have wrestled with for decades: Are supermode microcavity lasers single- or dual-mode?

    In pursuit of an answer, a team from Peking University has revealed the lasing dynamics of a stimulated scattering laser in a supermode microcavity. Experimentally, the team demonstrated the supermode microcavity laser’s single-mode nature.
