A Survey of Laser Lightning Rod Techniques
Abstract
The concept of using a laser to create an ionized path in the atmosphere to act as a lightning rod is not new. Over the past four decades since the invention of the laser, there have been many documented investigations into the ionization of atmospheric gasses with an eye towards creating a laser lightning rod. Initial experimental attempts using lasers operating in the IR were not successful. Although some ionization was attained, it was found that the laser beam was self-quenching so that distances of only tens of meters were obtained in the atmosphere near sea level. This paper briefly reviews the work which has been done in trying to create a laser lightning rod and discusses some ongoing research which has potential for achieving an operational laser lightning rod for use in the protection of missile launch sites, launch vehicles, and other property.
