Study Of High-octane Material As Laser Pumping Source

This paper deals with pyrotechnic mixtures which react fast and has high-energy output in near-infrared wave band (0.75 μ m and 0.81 μ m radiate area) and low-energy in visible light wave band, combining combustion theoretic of pyrotechnic mixtures and flame radiation theoretic. This pyrotechnic mixtures can replace xenon lamp as the pumping source of Nd:YAG lasers.The heat analysis of pyrotechnic mixtures selected realizes character of energy output and disciplinarian of physics and chemistry variety in the reaction course of pyrotechnic mixtures. Light output analysis tests character of spectrum radiate of pyrotechnic mixtures and analyses wave band distribute of light by comparing different static blaze spectrograms of the pyrotechnic mixtures. Screen out the better pyrotechnic mixtures according to request of pumping source. Press experiments in airtight erupt container experiment, which simulate the circumstance that pyrotechnic mixtures deflagrate in quartz pipe, realize the press influence to the quartz pipe wall and the disciplinarian of axes press variety. Apply these pyrotechnic mixtures to Nd:YAG lasers as the pumping source and compare pumping efficiency of different pyrotechnic mixtures. Pumping efficiency is an important standard which checkout if these pyrotechnic mixtures are the better pumping source. Sensitivity experiment analysis incarnate security of pyrotechnic mixtures that is the essential parameter in the process of design, manufacture and use.Radiate spectrum of Zr/NaNO₃, Zr/KNO₃ and Zr/KClO₄ He in 0.75 — 0.81 μm. Moreover, radiate spectrum of Zr/KClO₄ incline to the absorb spectrum of YAG bar. The experiment results, realize that Zr/KClO₄ is the better pumping source and pumping efficiency is higher.
