Abstract :
In order to study the extinction characteristics of black lead and black carbon to the laser of 1.06μm and 10.6μm. Based on Mie theory , calculated the extinction coefficient. Calculated the transmission with smoke thickness by using the theory of Lambert - Beer. Results show that black lead and black carbon have an optimal radius to make the extinction best and extinction characteristics of black lead sphere particles is better than that of black carbon during from 0.05μm to 0.16μm wavelength. In other wavelength range , the extinction characteristics of black carbon on smoke is better than that of black lead. The conclusion is helpful to the practical field application.
