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 �?typically solitary crystals (monocrystalline optical supplies) �?which are made use of as obtain media for good-point out lasers. Most often, They may be doped with possibly trivalent rare earth ions or transition steel 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 factors. The available pump resource (style of laser diode or lamp) plus the envisaged pumping arrangement are essential elements, but the fabric by itself also has some influence. For example, titanium–sapphire lasers should be pumped with substantial intensities, for which the form of the transversely cooled rod, operated with fairly compact pump and laser beam diameter, is much more suitable than e.
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。
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。
Laser modeling and simulation can be utilized to reliably determine the ideal crystal dimensions, doping density And perhaps values of additional parameters.

For quasi-a few-degree laser acquire media or simply 3-amount achieve media, 1 frequently ought to Restrict the size to a worth which is way too small for efficient pump absorption, as reabsorption results would usually spoil the performance. For side pumping, extra considerations arrive into Perform; Aside from effective pump absorption, it's important to obtain a suitable spatial condition on the gain 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 ought to have a substantial transparency (minimal absorption and scattering) in the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this will depend on the caliber of the fabric, based on information of the fabrication approach.
It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It can be set in some reliable mount which also acts being a heat sink. Bigger crystals are generally used for side pumping e.g. with superior-ability diode bars.
