【摘要】：为了提高结石碎石率和粉碎程度、减小碎石过程中副作用,采用电光调Q技术,设计了高峰值功率输出的纳秒钬激光碎石系统。从冷却温度、透过率、腔长等方面进行了理论分析,在冷却温度22℃、重复频率3Hz、抽运能量200J的条件下进行了实验验证,获得了腔内最大单脉冲能量443mJ、脉宽90ns激光输出的数据。结果表明,该系统可输出高峰值功率的纳秒钬激光,碎石时间短,可粉碎任何成分的结石,一次碎石率高,粉碎程度高。这为下一步产业化打下了基础。
[Abstract]:A nanosecond holmium laser lithotripsy system with high peak power output was designed by using electro-optic Q-switching technique in order to improve the rate and degree of lithotripsy and reduce the side effects in the process of lithotripsy. The theoretical analysis of cooling temperature, transmittance and cavity length is carried out. Under the conditions of cooling temperature 22 鈩，
