In this work, the influence of electric fields and atmospheric plasma on the behavior of an ultrafast femtosecond laser beam is being studied. A femtosecond laser pulse has an ability to self-focus in air and produce confined narrow channels of high energy density plasma, called filaments, which propagate over long distances. This technique has been employed in the remote initiation of electric discharges and has a potential to serve in lighting control, rain making, remote measurement of the electric field, microwave guidance and remote sensing of chemicals. Filamentation process requires a significant amount of energy (> GW), and the lasers used for that purpose are large and not easy to deploy and use. In this research, a possibility of using external high electric fields and low-temperature plasmas is explored to augment the laser beam operation, with the goal of lowering the power requirement on the laser. These external fields and plasmas are intended to act as stimuli to achieve filamentation of ultrashort laser pulses at a lower energy of the laser beam. Ultimately this approach may lead to a reduction of the size, weight, and power consumption of the laser system.
