摘要

在几乎所有的工业现场,各种激光系统由于其高能量密度、指向性和相干性等特点而得到了广泛的应用。目前在疑难杂症、诊断等医疗领域的临床应用越来越广泛。红宝石激光对去除纹身、雀斑等皮肤问题有最大的功效。而商用医用红宝石激光系统的最大重复频率为2Hz,光输出光束能量为1J。医生希望有一个高重复的红宝石激光系统,以减少手术时间。我们研究了一种新的双腔重复频率为4Hz的红宝石激光电源系统。此外,我们还利用2kW设计的LLC谐振变换器,开发了一种采用零电压开关(ZVS)的新型电源系统,以减小开关损耗。

Optimization of 4Hz medical ruby laser power system with dual cavities using multi-resonant converter
In almost all industrial site, various laser systems have been widely applied because of their characteristics such as high energy density, directivity and coherence. Nowadays the clinical application has become wider in medical parts such as incurable disease, diagnosis etc. Ruby laser has the greatest efficacy for removing tattoos, freckle and other skin problem. But commercial medical ruby laser system has the maximum repetition rate of 2Hz and optical output beam energy of 1J. Medical doctors want to have a high repetition ruby laser system to reduce the operation time. We investigated a new ruby laser power system having high repetition rate of 4Hz through dual cavities. In addition, we develop a new power supply system adopting zero voltage switching(ZVS) to minimize switching loss by LLC resonant converter designed by 2kW.
