摘要： In this paper we propose a one step marking process using a high power near infrared fiber laser and diffractive optical elements or gratings as an alternative to traditional scanning systems. The impact of the gratings fill factor, the power level on the diffracted beams and the quality of the reconstructed images are studied. We present simulation results of gratings diffraction efficiencies, experimental observations of gratings and DOEs behaviour illuminated with a fiber laser beam. We demonstrate that the fiber laser, showing good beam quality, can be used with standard diffractive structures with interesting results.
