治疗机。
Description
本发明属于光学薄膜和激光应用技术领域中的一种红外区双波长十倍频增透薄膜器件。它适应于Na:YAG和CO2两种激光并用的激光治疗机所使用聚焦透镜镀膜。
本发明以前与本发明最为接近的已有技术是0.53μm和1.06μm双波长倍频增透薄膜器件(出处“光仪技术”1985年第1期P50,作者王益聪等),可用于Na:YAG激光及其倍频激光应用,但该器件透射波长间距小,而且在基底和膜层材料方面均属可见和近红外区,并不涉及中红外波长区(第三透射窗口)的光谱透射问题。
公知的各种激光治疗机均使用特定波长激光器,如Ar+激光治疗机,工作波长为0.488μm和0.5145μm;Na:YAG激光治疗机,工作波长为1.06μm;CO2激光治疗机,工作波长为10.6μm等等。各种治疗机导光臂上所用聚焦透镜均选择在相应工作波长透射的基底并在基上涂镀该波长的增透膜。但是,这些镀膜的聚焦透镜都不能满足近红外和中红外波长区的两种激光同时使用。
为了克服上述缺点本发明的目的在于,并针对Na;YAG激光和CO2激光并用的光学系统,提出一种能满足1.06μm和10.6μm波长增透的薄膜器件。
本发明的详细内容如图1所示。1为薄膜器件的硒化锌晶体基底,2为涂镀的增透膜,其增透膜为单层膜,也可为双层膜,单层膜的涂镀材料采用氟化物,也可采用氟化物混合物,双层膜的涂镀材料采用氟化物和硫化物。
本发明的原理构思是选择在1.06μm和10.6μm波长均有较高透射率的基底和膜层材料,然后设计出在两个波长满足减反射条件的膜系,再用真空镀膜的方法制备出其薄膜器件。
图1为本发明的结构示意图,其中1-a为单层增透膜器件,1-b为双层增透膜器件。图2为最佳实施例结构示意图。
本发明的积极效果是Na:YAG和CO2两种激光可共用一个窗口和聚焦透镜,使Na:YAG激光机和CO2激光并用的新型激光治疗机研制并在临床应用成为可能。这样即发挥CO2激光所具有的快速切割和汽化长处,又保持有Na:YAG激光所持有的对机体深处穿透能力强和止血效果好的优点,从而大大提高治疗效果而优于其它激光治疗机。
本发明的最佳实施例如图2所示。3为硒化锌晶体基底,4为折射率和光学厚度满足减反射条件的氟化物或掺杂的氟化物混合材料单层增透膜。
