Abstract
This paper first introduces the emergence of laser optical and a variety of laser applications In the military and civilian aspects. And then, we have discussed the characteristics of Gaussian beam transmission and transformation by means of Fraunhofer diffraction ( Circular aperture diffraction, double-slit diffraction and the moment-hole ) of Gaussian beam. We have introduced platform MATLAB visualization tools ,and used MATLAB visualization platform to carry out simulation for the transmission of Gaussian beam and the Fraunhofer diffraction,get the graphics of transmission diffraction of Gaussian beam and hole Fraunhofer diffraction, double-slit diffraction, diffraction-hole moment , it is showed that simulation results are consistent with the theoretical analysis. Finally, outlook the main application areas and development of road in the future of the laser optics are given. Laser will be bright light for us to show.
Keywords： Gaussian beam;Fraunhofer diffraction;MATLAB Visual Simulation
