Abstract

We experimentally demonstrated remote sensing of the constituents of microparticles in air by combining laser-induced breakdown spectroscopy (LIBS) and lidar, using femtosecond terawatt laser pulses. Laser pulses of 70fs duration and 130mJ energy generated filaments when focused at a focal length of 20m and the pulses irradiated artificial saltwater aerosols in air at a 10Hz pulse repetition rate. Na fluorescence was observed remotely at a distance of 16m using a 318mm diameter Newtonian telescope, a spectrometer, and an intensified CCD camera. These results show the possibility of remote measurement of the constituents of atmospheric particles, such as aerosols, clouds, and toxic materials, by LIBS–lidar using femtosecond terawatt laser pulses.
