【摘要】：為了提高結(jié)石碎石率和粉碎程度、減小碎石過程中副作用,采用電光調(diào)Q技術(shù),設(shè)計了高峰值功率輸出的納秒鈥激光碎石系統(tǒng)。從冷卻溫度、透過率、腔長等方面進(jìn)行了理論分析,在冷卻溫度22℃、重復(fù)頻率3Hz、抽運(yùn)能量200J的條件下進(jìn)行了實驗驗證,獲得了腔內(nèi)最大單脈沖能量443mJ、脈寬90ns激光輸出的數(shù)據(jù)。結(jié)果表明,該系統(tǒng)可輸出高峰值功率的納秒鈥激光,碎石時間短,可粉碎任何成分的結(jié)石,一次碎石率高,粉碎程度高。這為下一步產(chǎn)業(yè)化打下了基礎(chǔ)。
[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，
