为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。

激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。

The utmost possible doping concentration can depend strongly to the host material and its fabrication method.

Several laser crystal elements happen to be shown where some saturable absorber content is included for passive Q switching of the laser.

For quasi-a few-degree laser achieve media or perhaps 3-amount obtain media, one usually really should limit the size to a worth that is far too small for efficient pump absorption, as reabsorption results would if not spoil the efficiency. For aspect pumping, more things to consider occur into play; Apart from effective pump absorption, it is necessary to acquire an acceptable spatial form with the obtain profile.

Distinctive crystalline components are really distinct regarding their hardness and various Qualities, which ascertain with which methods and how very easily they are often Lower and polished with high quality.

GWU-Lasertechnik has over 30 a long time of practical click here experience in distributing laser crystals. Pick out GWU to take pleasure in our large awareness and in-area practical experience!

There may be a variety of crystalline media, that may be grouped according to big atomic constituents and crystalline constructions. Some crucial groups of crystals are:

激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
