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 focus of the gain medium are most useful count on quite a few things. The readily available pump source (variety of laser diode or lamp) as well as envisaged pumping arrangement are crucial variables, but the material alone also has some impact. For example, titanium–sapphire lasers need to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with reasonably tiny pump and laser beam diameter, is a lot more acceptable than e.

Obviously, it is very desirable that a specified crystal high-quality is generated continually, While distinct laser styles can have another sensitivity to content 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。

Laser modeling and simulation can be used to reliably identify the ideal crystal Proportions, doping density and possibly values of supplemental parameters.

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-level laser get media as well as three-amount obtain media, one generally has to Restrict the length to a worth that is much too limited for productive pump absorption, as reabsorption effects would normally spoil the overall performance. For aspect pumping, additional issues occur into play; Aside from successful pump absorption, it's important to obtain an acceptable spatial condition of the acquire profile.

Diverse crystalline supplies are really distinct about their hardness and also other properties, which figure out with more info which procedures And the way easily they are often Slice and polished with good quality.

For various reasons, composite crystals are getting to be well-known. These have a spatially different chemical composition and might be manufactured with Particular styles.

There may be a variety of crystalline media, which may be grouped according to special atomic constituents and crystalline constructions. Some significant teams of crystals are:
