Profile Summary

Presently, I am working as a postdoc in the laser physics group of Prof. Nir Davidson at Department of Physics of Complex Systems, Weizmann Institute of Science, Israel. My research deals with degenerate cavity lasers and fiber lasers. More specifically, I am working on phase locking of coupled lasers network and spatial coherence study in degenerate cavity lasers.
