Active Remote Sensing Using Ultra Broadband Radiation.

Abstract

Active remote sensing using ultra broadband (UB) radiation has the potential to achieve identification of hazardous air pollutants (HAPs) at extended distances. The objective of this report is to propose and analyze the use of UB radiation for active remote sensing of HAPs. The UB source can provide day-night illumination of the pollution site with simultaneous multi-wavelength (continuum) radiation in the ultraviolet, visible or infrared regime. In addition, the UB radiation can be used in a multi-wavelength DIAL (Differential Absorption Lidar) configuration. One unique feature of this approach is the high average power achieved by using two long duration lasers at slightly different frequencies beating in a nonlinear medium. in addition, a demonstration experiment on the generation of UB radiation by this method is described.
