Measurements of Optical Kerr Nonlinearity n2 in Compressed Gases
Yury E. Geints, Victor O. Kompanets, Sergey V. Chekalin
High-power optical pulses experience self-focusing when propagating in a gaseous medium due to the manifestation of the cubic (Kerr-like) nonlinearity. The magnitude of this effect…
