The filaments, having made a plasma, turn the narrowband laser pulse into a broadband pulse having a wholly new set of applications. An interesting aspect of the filamentation induced plasma is the limited density of the electrons, a process which prevents the optical breakdown. This effect provides an excellent source for spectroscopy of high pressure with low level of continuum and also smaller line broadening. Another potential application is the LIDAR-monitori…
