Paper Abstract

An integrated DOE is designed for beam combination and shaping. The DOE is double-faced carved. One is transmission blazed grating to convert four declined incident incoherent beams to parallel beams, the other is continuous profile relief for shaping. The simulated intensity focal-plane profile has little modulation in the main lobe and high diffraction efficiency.
