摘要: 实验研究了308nm准分子激光皮肤治疗仪激光传输系统中光纤的传输特性。比较了三种不同类型的光纤:紫外扩展型液芯光纤、集束石英光纤、普通液芯光纤在不同的激光输出功率、工作时间等条件下的传输效率,紫外扩展型液芯光纤的传输效率达到70%;测量和分析在激光传输过程中液芯光纤对激光光强分布的改善和匀光作用,输出光束光场均匀性小于±4.5%。实验表明,基于液芯光纤的激光传输系统对于308nm紫外激光具有较好的激光传输效率、匀光效果和工作稳定性。

Abstract: Characteristics of optical transmission system with liquid-core optical fiber used for 308nm Excimer Laser instrument in Vitiligo treatment were studied. The optical transmission under different laser power output and operation time of three different fibers were tested and compared. These fibers included UV extended liquid-core optical fiber, silica bundled fiber and ordinary liquid-core optical fiber. The transmissivity of UV extended liquid-core optical fiber was as high as 70%. The intensity distribution and beam homogenization via optical fiber were measured and analyzed. The beam homogenization via UV extended liquid-core optical fiber was less than 4.5%. The results showed that transmission system based on liquid-core optical fiber for 308nm UV laser has better transmissivity , homogenization and stability.

Key words: laser technique, 308nm Excimer Laser, transmissivity, liquid-core optical fibe, optical transmission system, homogenization
