Diagnostics of ultrashort laser pulses

We develop new schemes for diagnostics of ultrashort laser pulses. In Ref. [1], we reported a new approach for FROG

Welcome. You (somehow) arrived to the webpage of the Technion ultrafast optics group headed by Prof. Oren Cohen. We explore several frontiers in optics, particularly in high-field ultrafast optics, including

 

 

 

 

    • Soleakons: self-trapped leaky waves.

We typically have openings for highly motivated researchers in all levels: undergraduate students, graduate students and post-docs.
