Extinction Coefficient of Red Phosphorus Smoke Combined with Nanometer Iron Powder to 10.6 Microns Laser Emission
In order to improve the extinction performance of red phosphorus smoke to 10.6um laser emission, the extinction coefficients of red phosphorus smoke, nanometer iron aerosol and their combined smoke to 10.6um laser emission were tested in a middle-size smoke chamber. Under the condition with an air relative humidity of 43％ and temperature 19℃, the extinction coefficients of red phosphorus smoke, nanometer iron aerosol and their combined smoke to 1.0 W 10.6um laser emission are 0.391m2/g, 0.084m2/g and 0.469m2/g. By the experimental results, when red phosphorus smoke is combined with nanometer iron aerosol, the diffusion performance of nanometer iron power will be remarkably improved and the extinction coefficient of the combined smoke may be enhanced 20％ compared with red phosphorus. With the increase of air relative humidity, the extinction performance of the combined smoke will be enhanced.
