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。

Moreover, some versatility is lost in experiments if a person simply cannot Check out absorbers with diverse thickness or doping concentration, by way of example, without the need of exchanging the laser crystal by itself.

作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

Obviously, it is vitally fascinating that a given crystal top quality is created persistently, although various laser models might have another sensitivity to material parameters.

亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。

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-a few-amount laser gain media or maybe 3-degree gain media, a person typically really should Restrict the duration to a value which is way too brief for productive pump absorption, as reabsorption results would in any other case spoil the functionality. For aspect pumping, extra things to consider arrive into Engage in; Moreover successful pump absorption, it is important to get a suitable spatial shape of the acquire profile.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

The medium must have a superior transparency (minimal absorption and scattering) within the wavelength locations of click here pump and laser radiation, and fantastic optical homogeneity. To some extent, this relies on the quality of the fabric, based on facts on the fabrication procedure.

With that concept, 1 will not require a further saturable absorber crystal, making sure that a person may perhaps make a lot more compact Q-switched laser setups with decrease inside parasitic losses. Nevertheless, unwelcome Negative effects might also take place, for example acquiring unwanted valence states from the involved ions or energy transfers.

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。
