These tables include only the commonest host crystals; many Some others exist, which can be fewer routinely 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。
激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
Which geometry, dopant and doping concentration from the attain medium are most advantageous rely upon quite a few factors. The accessible pump supply (type of laser diode or lamp) plus the envisaged pumping arrangement are important things, but the material itself also has some impact. By way of example, titanium–sapphire lasers should be pumped with large intensities, for which the form of a transversely cooled rod, operated with fairly modest pump and laser beam diameter, is a lot more appropriate 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。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-three-level laser obtain media as well as three-degree achieve media, a person often must limit the size to a value that is as well quick for successful pump absorption, as reabsorption consequences would if not spoil the overall performance. For side pumping, extra factors arrive into Engage in; Moreover successful pump absorption, it is crucial to acquire an appropriate spatial form on the achieve profile.

In 2017, we produced the world’s major Ti∶sapphire crystal (Φ235 mm), which supported The ten PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with incredibly broad emission spectra drives the development of laser diode pumped ultrafast stable-point out lasers. With the increase in pulse Electricity, peak energy, and repetition charge of reliable-point out lasers, laser crystals will build toward larger measurements, increased crystal excellent, and controllable essential functionality.
There is certainly a wide array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline buildings. Some significant groups of crystals are:
