The invention relates to a diffuser applied to a laser projection device. The diffuser includes N microstructures for diffusing incident circular light beams, and N is a positive integer greater thanor equal to 10. Each of the N microstructures has first and second sections perpendicular to each other, and the diffusion angle of the second section is larger than that of the first section. When the diffuser in the embodiment of the invention is applied to a laser projection device, the original circular excitation spots can be changed into elliptical spots. On one hand, the excitation spot area of fluorescent powder is increased, the power density of excitation light is reduced, and higher excitation light power can be withstood. On the other hand, the unused area of light bars can be utilized to increase the fluorescence absorption of the light path.
