title: Control of filamentation induced by femtosecond laser pulses propagating in air.
abstract: Filamentation formed by self-focusing of intense laser pulses propagating in air is investigated. It is found that the position of filamentation can be controlled continuously by changing the laser power and divergence angle of the laser beam. An analytical model for the process is given.
