The most typical laser-active uncommon earth ions and host media together with some common emission wavelengths are shown in the subsequent 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。

Laser crystals are optical crystals �?generally one crystals (monocrystalline optical materials) �?which can be used as achieve media for good-state lasers. Usually, They're doped with both trivalent exceptional earth ions or changeover metal ions.

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 aspects. The accessible pump source (variety of laser diode or lamp) as well as envisaged pumping arrangement are very important variables, but the material alone also has some influence. For instance, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with comparatively little pump and laser beam diameter, is much more proper than e.

Naturally, it is rather appealing that a given crystal quality is manufactured continually, Despite the fact that distinct laser designs might have a distinct sensitivity to material 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。

For quasi-3-stage laser attain media as well as three-level gain media, a person typically must Restrict the duration to a price which is way too short for productive pump absorption, as reabsorption consequences would normally spoil the overall performance. For aspect pumping, extra criteria come into Engage in; Other than effective pump absorption, it is necessary to acquire an acceptable spatial form on the get profile.

Diverse crystalline materials are certainly distinct about their hardness along with other Houses, which figure out with which procedures and how quickly they may be Lower and polished with top quality.

GWU-Lasertechnik has a lot more than 30 several years of practical experience in distributing laser crystals. Pick out GWU to reap the benefits of our broad understanding and in-industry experience!

There's an array of crystalline media, which may be grouped read more in accordance to special atomic constituents and crystalline constructions. Some significant 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。
