【摘要】 对干燥状态和浸水后的红砂岩、花岗岩、大理岩在不同超短脉冲激光入射频率和烧蚀发次等条件下的烧蚀情况进行了研究.结果发现,浸水后的岩石烧蚀质量损失明显大于干燥状态下的质量损失.同时质量损失与激光入射频率和烧蚀发次有着密切的关系.更多还原

【Abstract】 The interaction of ultra-short laser pulses with rocks at different laser frequency and ablation shots are investigated under the conditions of dry and water immersed.The results show that the mass loss under the condition of water immersed is much higher than that in dry condition.Moreover,the mass loss is intimately dependent on laser frequency and ablation shots.更多还原
