Discovery of Several New Families of Saturable Absorbers for Ultrashort Pulsed Laser Systems

Abstract Saturable Absorber (SA) is a key element of any passive mode-locked laser system to provide ultrashort laser system. So far various materials have been proposed that could be used for this purpose. However, the field is still looking for new ways to make the fabrication process easier and c...
