| 摘 要： | 为了广泛适用于多种眼科疾病的激光治疗,介绍了一种可以产生红、黄、绿三色激光的眼科治疗系统。在此系统中,使用2台全固态激光器,通过倍频分别获得红、绿光,再通过光纤耦合及光纤混频,实现红、黄、绿三色激光根据使用需要单独工作或者同时工作。其中红外基频光1320 nm与1064 nm分别达到26 W与47 W;660 nm红光与532 nm绿光分别达到1 W与1.9 W,单独光纤输出分别达到0.8 W与1.5 W;并实现Y型光纤混频输出功率达到1.6 W。该系统能使红、黄、绿三色激光发挥在眼科治疗中各自的优势,并互补不足。

| Abstract: | The more wavelengths can be generated,the more retinopathy can be cured.An equipment which can generate laser in three colours,red,yellow and green is introduced.It can be appled in diverse retinopathyes.There are two all-soild-state lasers in this equipment.It can work with only one wavelength mode.It also can work with three wavelengths mode by means of fibre coupling and optical mixing.The power of the fundamental frequency light is respectively 26 W and 47 W at the wavelengths 1320 nm and 1064 nm.The po... |
