报道了用Q开与YAG激光器在金属中激励超声脉冲,以及激光能量、材料表面状况和材料中人工缺陷对激光激励超声脉冲影响的研究结果,它对于研究激光与物质的相互作用以及将激光超声用于无损检测都是有益的。
This paper reports the results of the study on the laser-substance interaction and the laser-induced ultrasonic pulse excited by Q-switched and YAG-based lasers and their effects on laser pulses, laser energy, surface conditions and artificial defects in materials. For non-destructive testing are beneficial.
