摘要
用凸透镜将钬激光器输出脉冲激光耦合进大芯径光纤传输,测量了耦合后激光能量、脉冲宽度和重复频率,研究了脉宽对激光脉冲消融猪肝组织的影响.实验结果表明:随着激光脉宽的增加,凹坑和受损伤组织的体积均增大.
Holmium laser pulses were coupled into a large-diameter fiber via lens. Laser parameters such as energy, pulse width and repeat frequency were measured. The influence of pulse width on the ablation of pork liver was investigated. The results indicated that the volume of pit and injured tis- sue increased when the pulse width increased.
