摘　　要：In this paper,a digital laser with a dual-cavity configuration for the pattern control of a Q-switched pulsed laser is presented.The dynamic pattern control of the pulsed laser from the primary cavity is generated and controlled by simply manipulating the projected phase of the spatial light modulator(SLM)in the secondary cavity.The proposed digital laser design provides a solution for a flexible pulsed laser source while preventing damage to the SLM from high-peak light pulse flux density,benefiting structured laser applications that require high-peak laser power.
