[原创]俺的LD泵浦高功率绿光(图)
下面的是我做的LD泵浦高功率绿光,最高70多W,10KHZ,脉宽80ns<img src="data/attachment/forum/dvbbs/2005-4/2005418225863066.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'data/attachment/forum/dvbbs/2005-4/2005418225863066.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

下面是我做过的LD泵浦高功率绿光光纤耦合实验,100W绿光,10m光纤打了200个小时,效率90%以上.

还有就是,你开始说最高功率是70W,怎么后来又用100W的做耦合实验呀。

光纤激光器不是固体激光器吗? 楼主咋不理大伙??看样子不像光纤激光器。
LD是什么样的?单根光纤或光纤束?? 我指的固体激光器当时是用晶体棒作介质的激光器呀。
如果不是光纤的,那功率也太高了吧,厉害哦。
强烈要求楼主讲一讲大概的工作原理,学习一下,谢谢。哈
绿光能做成这么大,激光器还这么小,厉害 你的晶体的热沉怎么设计的,这么大功率很容易烧坏晶体的吧 不是光纤激光器,是典型的ND:YAG倍频的结构,L腔KTP内腔倍频激光器.棒长90mm,d=5mm,LD的泵浦功率500W.最下面的那个图是用了另一个106W的绿光固体激光器进行的光纤耦合传输实验.光纤耦合装置要是设计的好的话是不会烧的,当然这里也有一些窍门的.
