These tables comprise only the most typical host crystals; quite a few Other people exist, which can be much less commonly employed.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
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。
Which geometry, dopant and doping concentration on the achieve medium are most beneficial depend on numerous components. The obtainable pump source (type of laser diode or lamp) as well as the envisaged pumping arrangement are very important components, but the material by itself also has some impact. Such as, titanium–sapphire lasers need to be pumped with large intensities, for which the shape of a transversely cooled rod, operated with comparatively modest pump and laser beam diameter, is much more proper than e.
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。
Needless to say, it check here is vitally appealing that a supplied crystal high quality is developed consistently, Despite the fact that different laser styles may have another sensitivity to materials parameters.
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。
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。
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。
It is apparent that various purposes produce really unique prerequisites on laser attain media. Because of this, a broad array of different crystals are employed, and building the appropriate decision is important for setting up lasers with optimum performance.
