一个多波长激光系统，设计用于精确和有效的组织消融在水下实现的同时耦合辐射的钬：YAG激光器，发射波长为2.12 μ m和铒：YSGG激光器在2.79 μ m到相同的氟化锆（ZrF4）的纤维。两个激光器的光路共线结合，利用一个棱镜的色散。快速视频闪光照片和激光诱导的压力瞬变同时记录与PVDF压力传感器被用来研究气泡形成的动力学在浸没的纤维尖端。气泡的尺寸和气泡的寿命被确定为波长和两个不同的激光脉冲之间的延迟时间的函数。结果表明，2和3 μ m辐射的组合利用了两种波长的特定优势，并大大提高了水下组织的消融效率。(C)1995年美国物理学会。
A multiwavelength laser system designed for precise and efficient tissue ablation under water was realized by simultaneously coupling radiation of a holmium:YAG laser, emitting at a wavelength of 2.12 mu m and an erbium: YSGG laser at 2.79 mu m into the same zirconium fluoride (ZrF4) fiber. The beam paths of the two lasers were collinearly combined taking advantage of the dispersion of an Infrasil prism. Fast video flash photographs and laser induced pressure transients simultaneously recorded with a PVDF pressure transducer were used to study the dynamics of bubble formation at the submerged fiber tip. The bubble size and the bubble lifetime were determined as a function of the wavelength and the delay time between the two different laser pulses. The results indicate that the combination of 2 and 3 mu m radiation takes specific advantage of both wavelengths and strongly enhances the ablation efficiency of tissue under water.
