摘　　要：分别利用脉宽在40 fs和5 ns的飞秒及纳秒激光脉冲加工了钎焊在不锈钢底板上的金刚石阵列。通过测量加工区域面积和入射激光功率的关系推断出了飞秒和纳秒激光脉冲加工金刚石材料的阈值。实验结果表明,相比于纳秒激光加工,利用飞秒激光加工金刚石的阈值更低。也利用显微镜比较了利用不同种类光源加工金刚石后加工区域的形貌。研究结果证明了利用飞秒激光加工金刚石相比于纳秒激光更为有效。Diamond array was braze welded on the stainless steel substrate which was processed applying femtosecond and nanosecond laser pulses with pulse duration 40 fs and 5 ns, respectively. The threshold of diamond processed using femtosecond and nanosecond laser pulses was deduced by measuring the relationship between fabricated area and laser power. The processing results show that the threshold of diamond processed by femtosecond laser pulses is lower compared with that processed by nanosecond laser pulses. The morphology of the processed region using differentkinds of laser sources was also compared with microscope. The processing of diamond applying femtosecond was confirmed more effective than that using nanosecond pulses.
