Filamentation nonlinear optics: a new frontier

The filament core of a femtosecond laser pulse propagating in an optical medium has extra-ordinary quality for exploitation that includes high quality tunable pulse generation from the UV to the THz. The peak intensity inside the filament is also high enough to dissociate/ionize any molecules resulting in remarkably distinct spectra which can be use for remote sensing of Chem-bio agent.
