Air Lasing as a remote sensing tool

The emission of laser – like back-propagating radiation has great potential as a remote sensor. In general, the bottleneck of remote sensors is the signal intensity of the back-propagating radiation carrying the information from the remote point and its dependence on the local magnetic field.


Detecting and monitoring the chemical and physical characteristics of an area at a distance has been long recognized as a powerful tool for acquiring information and is utilized extensively in various fields spanning from Earth sciences to humanitarian applications. In particular, remote sensing of magnetic fields is significant for, e.g., understanding of the nature of the geomagnetic fields, early earthquake warnings (See Comment on earthquake early detection) and magnetic substances in the ground, which, in contrast to stellar magnetic fields, have never been studied remotely.
