现有的铥激光发射器为单管单波长发射形式，其发射的铥激光虽然水吸收率高，便于组织气化，且多用于碎石手术之中，但是铥激光波长特性决定其血红蛋白吸收率极低，无法应用于医学美容领域。

为了更清楚地说明本实用新型的具体实施方式，下面提供一种实施例：
本实用新型的一种固态脉冲铥激光和绿激光协同输出的医用激光器，其具体部件功能及规格如下：
1、铥棒规格为φ4*102mm，其两端各有16mm键合部分连接键合支架17，用于减小热透镜效应，便于钯条散热。
2、钯条分为三组，每组钯条上固接6个氨聚光钯点20，每个钯点输出功率为60W，其向钯条输出750～800nm的半导体波，其总功率为1080W。
3、声光调Q用于将连续的激光调制成脉冲光波，其采用现有技术中的成熟产品。
4、第二全反镜用于反射铥棒投射的2025nm波长的平行光照，该第二全反镜与5％光谱输出镜之间配合形成谐振腔，在该谐振腔内2025nm波长的铥激光反复通过铥棒与声光调Q并产生谐振放大效应。该第二全反镜规格为φ18*3mm，其表面镀2025nm波长的全反膜。
5、5％光谱输出镜规格为φ18*3mm，其中心穿透波长为2025nm，输出率为5％；剩余95％的2025nm波长铥激光反射回谐振腔内谐振放大，其可以将最初发生的2025nm波长铥激光的输出功率放大20倍以上。
6、第二45°全反镜中心镀2025nm波长铥激光的全反膜，其规格为φ40*3mm。
7、窗口镜规格为φ18*6mm，其中心镀2025nm波长铥激光的增透膜，其主要起到隔离密封作用，可对铥激光发生腔、绿激光发生腔及混光腔进行有效的透光密封分隔。
8、第一45°全反镜镀2025nm波长铥激光的全反膜以及532nm波长绿激光的增透膜，其采用现有技术中规格为φ40*3mm的三维可调镜。
本实用新型的一种固态脉冲铥激光和绿激光协同输出的医用激光器，其工作原理如下：
钯条通电时其发出750～800nm半导体波并投射向铥棒，当半导体激光达到一定速度时铥棒受激产生出2025nm的铥激光，经过第二全反镜和5％光谱输出镜之间配合形成谐振腔对铥激光进行谐振放大，并且谐振腔内连续的铥激光通过声光调Q调制成脉宽1μs的脉冲波输出，输出的脉冲铥激光经第二45°全反镜及窗口镜透射，并在混光腔内与532nm波长的绿激光混合，最终经第一45°全反镜反射至光纤中输出，需要注意的是在第一45°全反镜与光纤之间的混光腔内还固装有现有技术中的聚焦镜23。
本实用新型的一种固态脉冲铥激光和绿激光协同输出的医用激光器，其采用侧面照射原理刺激铥棒及掺钕钇铝石榴石棒，其三个照射点分别呈等腰三角形分布，用以保证铥棒及掺 钕钇铝石榴石棒的受激面积，其输出的脉冲铥激光峰值功率达3万瓦以上；脉宽是1μs。
最后，本实用新型的未述之处均采用现有技术中的成熟产品及成熟技术手段。
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本实用新型所附权利要求的保护范围。
