Abstract

A technique for using two lasers operating in tandem to remotely ignite oil pools in the harsh Arctic environment has been developed. A CW CO2 laser "preheats" a localized area of the oil pool for several seconds, thereby raising the surface temperature above the fire-point. A fire is then ignited by a focused high-power pulse from a second laser. The fire sustains itself and spreads when the absorbed laser energy is distributed, by convection in a thin surface layer, over a sufficiently large area. An optical system has been designed which allows the laser beams to be focused and directed onto oil pools from a helicopter.
