（3）当光栅厚度变大时,光栅的波长变化变小,旁瓣高度变大；（4）当光栅线对增大时,光栅的波长变化变小,旁瓣高度变化不明显.进一步探讨了高斯光束通过光栅后的变化,可知：若以高斯光束入射光栅,出射的衍射波理论上也应该为一个高斯光束,不同的是,出射高斯光束的振幅和相位与入射相比有所变化.

3) When the thickness of grating size,the grating changes the wavelength become smaller,the high sidelobe large; (4) When the grating line on increases,the grating wavelength smaller sidelobe height did not change significantly.To further explore the Gaussian beam through the grating after the change,we can see:If the incident Gaussian beam grating,the diffraction of radio-wave theory should be a Gaussian beam,different yes,a shot of the Gaussian beam amplitude and phase with the incident compared to change.
3) works as when diffraction grating thickness fill-out,the diffraction grating wave length change changes is small,the side lobe increases highly; (4),when light grating to enlargement,the diffraction grating wave length change changes is small,the side lobe change is not highly obvious.Has further discussed the Gauss light beam after the diffraction grating change,may know:If take the Gauss light beam incidence diffraction grating,the projection diffracted wave should also as a Gauss light beam theoretically,what is different,projects the Gauss light beam oscillation amplitude and the phase and the incidence compares has the change.

(3)The wave-length variety of light grid diminishes while pawning everything grid thickness to become big, the side petal highly becomes big;(4)Pawn everything grid line to diminish towards enlarging, light the wave-length variety of the grid, side petal height the variety isn't obvious.After further inquiry into Gauss lighting beam to pass only a grid of variety, can know:If goes into to cast light grid by Gauss light beam, the Yan for shooting shoots wave theoretically should also be a Gauss light beam, dissimilarity of BE, shoots Gauss light beam of flap and mutually with go into shoot to compare to have variety.
