Blog Article

These tables have only the commonest host crystals; numerous Some others exist, which can be fewer often utilised.

Here you'll be able to submit issues and opinions. In terms of they get recognized because of the creator, they can surface above this paragraph along with the creator’s remedy. The writer will make a decision on acceptance dependant on sure standards. In essence, the issue must be of adequately broad desire.

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。

In addition, some overall flexibility is dropped in experiments if one particular are unable to try out absorbers with distinct thickness or doping focus, for instance, with out exchanging the laser crystal alone.

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。

A high surface excellent is obviously significant. Technical specs of area flatness tend to be a lot better than . This helps in order to avoid equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. In addition, scratch and dig technical specs

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

Laser modeling and simulation may be used to reliably decide the the best possible crystal dimensions, doping density And maybe values of extra parameters.

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

For quasi-3-level laser acquire media or even 3-level attain media, one particular frequently really should limit the duration to a value and that is also small for economical pump absorption, as reabsorption results would if not spoil the efficiency. For facet pumping, additional issues occur into play; Aside from successful pump absorption, it is necessary to acquire an appropriate spatial form with the attain profile.

Various crystalline products are quite various relating to their hardness along with other Attributes, which decide with which procedures and how simply they may be Reduce and polished with high quality.

GWU-Lasertechnik has much more than thirty yrs of expertise in distributing laser crystals. Choose GWU to take pleasure in our huge understanding and in-discipline knowledge!

There may be a variety of crystalline media, that may be grouped in accordance to important atomic constituents and crystalline structures. Some click here 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。
