Efficient terahertz and Brunei harmonic generation from air plasma with femtosecond two-color mid-infrared lasers

Not Accessible

Your library or personal account may give you access

Abstract

We report the generation of coherent radiation from terahertz to ultraviolet via two- color mid-infrared laser mixing in air. We achieve laser-to-terahertz conversion efficiency of ~1%, 10~100 times greater than those obtained with 800 nm lasers.
