Laser beam compressed into thin filament

Laser beam compressed into thin filament

June 2, 2015: A group of Russian scientists recently presented their research into the process of laser pulse filamentation?the effect produced when a laser beam propagating in air focuses into a filament. The researchers discovered how this process influences the preliminary transition of a beam passing through quartz glass, which has applications in the field of nonlinear optics. What is ...
