1. Nd:YAG rod
2. Laserbeam
3. Output coupler mirror
4. Diode arrays
5. Collimating optic
6. High-refelectance
7. Cooling
8. Electrical supply

The optical excitation is done by high power diode laser modules, which are radially arranged around the Nd:YAG rod. The resonator is coaxial with the laser rod, and consists of a high-reflectance mirror and a partial-reflective output coupler. Several diode pumped rods may be arranged in series in order to achieve output powers in the multi-kW range. The laser beam can be deliverd by using one or several fibers.

rofin 的激光器，结构原理！
如果大家觉得有用就顶啊！：）

自己画的，还是网上当的？对OPTEX的193nmArF气体激光器的原理了解么？？？

solojackie · 发表于 2003-7-9 16:13:00

在网上当的，我对固体激光器的原理还比较了解，对气体的工作原理就不懂了！
不过，可以帮你查一下！！：）

一目了然，很好！

好。。灌水。。顶

画的不错，
可是半导体激光器（侧边出光和纵向垂直出光两种）的还没有呀？
我自己设计了一个高功率激光器，不知是否可行，让各位见笑了，

我再描一下：
其中的二极管当然是激光二极管了，
也可以是经过微聚焦的激光大功率光纤阵列，
以后的航天激光通讯大概就是这样的吧？
工业加工上也可以考虑这种简单的输出功率叠加、汇聚法？

当然透镜组可能要有一点冷却系统了，

楼上的结构也可以用在端泵的半导体激光器中，是其中的一种耦合方式，当然用光纤要好一些。

the collimating and focusing optics consists of two cemented doublets and a precision opotimized aplanatic meniscus lens,as shown in the figure above,this configuration produces a smaller beam spot than when a single doublet is used ,without lowering the performance .the first doublet is used to collimate the laser beam coming from the fiber ,the exit surface of which should be placed in the focal plane of the first doublet .using this system ,the laser beam can be focused to a beam spot of 0.5mm in diameter.
