The most typical laser-Lively exceptional earth ions and host media along with some common emission wavelengths are shown in the following desk:

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 from the acquire medium are most advantageous depend on several factors. The available pump supply (form of laser diode or lamp) as well as envisaged pumping arrangement are crucial variables, but the material alone also has some affect. As an example, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with reasonably little pump and laser beam diameter, is a lot 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。

Not surprisingly, it's very appealing that a presented crystal good quality is made constantly, Even though distinctive laser models can have another sensitivity to substance parameters.

The most possible doping focus can count strongly about the host materials and its fabrication process.

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。

It is clear that different applications lead to extremely various needs on laser obtain media. For that reason, a broad range of various crystals are applied, and earning the appropriate alternative is essential for constructing lasers with the best possible functionality.

Distinct crystalline materials are certainly various relating to their hardness click here as well as other Houses, which determine with which approaches And exactly how effortlessly they are often Slice and polished with good quality.

For numerous factors, composite crystals are becoming preferred. These Use a spatially various chemical composition and can be designed with Specific shapes.

You can find an array of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. 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。
