Metasurfaces help lasers to mode-lock

HIGHLIGHTS

  • who: Basudeb Sain from the (UNIVERSITY) have published the research: Metasurfaces help lasers to mode-lock, in the Journal: (JOURNAL)
  • how: The results showed that a metasurface made of plasmonic nanostructures has the potential to be a SA for passive mode-locking in laser cavities.

SUMMARY

    Metasurface saturable absorbers may result in versatile mode-locking that allows one to obtain stable ultrashort laser pulses with high repetition rates and peak powers, along with broadband operation, within fiber to solid-state laser cavities. Saturable absorption is a nonlinear optical effect where the . . .
