Study On Preparation And Protective Properties Of The Composite Laser Protective Materials

With the wide use of laser technology, the laser becomes a growing threat to the human eyes and photoelectric sensors and laser protection technology draws more and more attention. The linear absorption protection technology accounts for an important position in the laser protection technology for its advantages including unrestricted protective angle, ease processing, low cost and so on.In this dissertation, the composite laser protective material was studied against694nm wavelength of ruby laser,1060nm wavelength of YAG laser and its frequency doubling530nm wavelength. Three laser absorbents were synthesized and selected, the optimum synthesis conditions, structures and properties of the prepared compounds were analyzed and tested. The synthesized three laser absorbents were added to the polycarbonate resin, the composite laser protective material sample was prepared by the means of injection molding method. The testing results showed that its laser protection optical density was over3at three wavelengths the three wavelength and it can be used as laser protective materials.
