The commonest laser-Lively scarce earth ions and host media along with some regular emission wavelengths are revealed in the following desk:
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 �?ordinarily solitary crystals (monocrystalline optical products) �?that happen to be utilized as achieve media for solid-condition lasers. Usually, They are really doped with either trivalent rare earth ions or changeover metallic 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 of your gain medium are most beneficial depend upon a number of elements. The accessible pump resource (variety of laser diode or lamp) as well as envisaged pumping arrangement are crucial variables, but the material alone also has some impact. For instance, titanium–sapphire lasers have to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with reasonably little pump and laser beam diameter, is a lot more appropriate than e.

A significant area high quality is naturally vital. Specifications of surface flatness are frequently a lot better than . This will help in order to avoid equally scattering losses and wavefront distortions which often can degrade the laser's beam high-quality. In addition, scratch and dig technical specs
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。

For quasi-a few-level laser attain media and even three-amount achieve media, a person frequently ought to limit the length to a value that's much too short for economical pump check here absorption, as reabsorption outcomes would otherwise spoil the overall performance. For aspect pumping, further concerns arrive into Engage in; Apart from successful pump absorption, it is crucial to get a suitable spatial shape from 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。
For different factors, composite crystals are getting to be well known. These Possess a spatially different chemical composition and might be produced with Exclusive shapes.
It might be oriented for in close proximity to perpendicular incidence with the laser beam, or at Brewster's angle. It might be preset in certain good mount which also functions for a warmth sink. More substantial crystals usually are employed for aspect pumping e.g. with large-electrical power diode bars.
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。
