The results indicate that multiple reflections are favorable to the increase of depth. When the focal position is above the surface, the absorptive intensity on the front decreases, so the cutting depth decreases. When the focal position is below the surface, the position on the front with the maximum power intensity is downward. The intensity distribution is toward the deeper position, the cutting depth increases. But if the negative focal distance is extremely big, the intensity of the deeper position attenuates sharply with the increase of focal radius and light distances, so the depth deceases.

正离焦切割时，前沿吸收的总激光功率密度减小，切割深度减小；负离焦切割时，最大激光功率密度值的位置下移，使得前沿功率密度分布朝着深部推进，切割深度增加，若负离焦量过大，表面光斑直径和光程增加，更深位置的功率密度减小，切割深度减小；随着激光功率增加、切割速度减小，则前沿弯曲程度减小，被激光直接照射的前沿部位增长，前沿吸收激光功率密度增加，切割深度增加。
