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。
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and in addition the higher-state life span.
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。
A significant floor top quality is certainly significant. Technical specs of floor flatness in many cases are better than . This aids to prevent the two scattering losses and wavefront distortions which might degrade the laser's beam excellent. On top of that, scratch and dig specifications
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。
A few laser crystal components are shown the place some saturable absorber materials is included for passive Q switching of a laser.
量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。
These surfaces that happen to be handed by the laser beam are normally both oriented at Brewster's angle or have an anti-reflection coating.

The medium must have a large transparency (small absorption and scattering) in the wavelength areas of pump and laser radiation, and superior optical homogeneity. To some extent, this is determined by the standard of the material, based on aspects in the fabrication procedure.
There is a wide range of crystalline media, which can be grouped according to important atomic constituents and crystalline structures. Some essential groups of crystals are:
