These tables contain only the commonest host crystals; several others exist, which are a lot less regularly made use of.
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（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。
This is straightforward to try and do: just find the lock icon before the URL inside the handle bar and drag that for the bookmark toolbar Using the mouse. Just in case you find the bookmark entry much too extended, you can appropriate-simply click it to edit the text, e.g. employing "RP Enc" rather than "RP Photonics Encyclopedia".

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。
g. a thin disk. As another case in point, Q-switched lasers achieve a higher populace density in the higher laser degree and so are thus a lot more delicate to quenching effects and Electricity transfer procedures; as a result, a lessen doping density is often appropriate for these products. For high-electrical power lasers, lessen doping densities are frequently accustomed to limit the density of heat era, While slender-disk lasers operate most effective with highly doped crystals. Many laser goods usually do not reach the total effectiveness probable mainly because these facts have not been properly worked out.
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 clear that diverse purposes bring about pretty distinct prerequisites on laser obtain media. For this reason, a broad variety of various crystals are utilized, and producing the ideal decision is important for developing lasers with optimum functionality.

The medium must have a superior transparency (minimal absorption and scattering) in the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined by the standard click here of the fabric, based on details from the fabrication approach.
There may be a wide range of crystalline media, that may be grouped according to big atomic constituents and crystalline buildings. Some significant teams of crystals are:
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
