In this article you are able to submit queries and responses. So far as they get acknowledged because of the author, they may surface earlier mentioned this paragraph along with the writer’s remedy. The creator will determine acceptance based on particular criteria. Primarily, The difficulty need to be of sufficiently wide fascination.

芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。

Additionally, some overall flexibility is lost in experiments if a single cannot try out absorbers with distinctive thickness or doping concentration, by way of example, without the need of exchanging the laser crystal alone.

Which geometry, dopant and doping concentration in the obtain medium are most advantageous rely on a number of elements. The readily available pump supply (sort of laser diode or lamp) as well as the envisaged more info pumping arrangement are essential aspects, but the material alone also has some affect. By way of example, titanium–sapphire lasers must be pumped with significant intensities, for which the form of the transversely cooled rod, operated with rather smaller pump and laser beam diameter, is much more suitable 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。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

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。

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

For various reasons, composite crystals are becoming preferred. These Have got a spatially various chemical composition and may be produced with special styles.

There may be a variety of crystalline media, which can be grouped in accordance to important atomic constituents and crystalline structures. Some critical teams 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。
