Abstract
For the laser spot size, the blazed diffractive grating fabricated with direct laser writing will has a slantwise lateral facet edge. To evaluate the influence of the slope of the facet edge of blazed diffractive grating, we calculate the diffraction efficiencies in +1 order and zero order as a function of the angle for the slantwise lateral facet edge with rigorous coupled wave analysis. As the lateral facet edge is getting more slantwise, the diffraction efficiency in +1 order decrease more, which degrades the image quality in monochromatic imaging. But the diffraction efficiency in zero order always keeps very low to assure the application in optical limiting.
