皮秒和纳秒YAG脉冲激光离体血管成形术的实验研究

Separate Experimental Study of Angioplasty with Picosecond and Nanosecond YAG Pulse Lasers

采用皮秒和纳秒YAG激光脉冲分别对试管内血栓、猪主动脉血栓及猪动脉血管壁进行了详细的激光气化实验研究。给出样品气化深度与激光脉宽、波长、单次脉冲能量和辐射总能量的关系曲线,并对样品作了组织学检查。

We have done detail laser vaporized experimental study on thrombus in tube, pig's main artery and arterial wall under separate condition with picosecond and nanosecond YAG pulse lasers.We have shown out several curves about sample vaporized depth and laser pulsewidth, wavelength, single pulse and total radiate energy. Histological inspection have been studied on experimental samples.
