Laser crystals are optical crystals �?typically one crystals (monocrystalline optical elements) �?that happen to be applied as get media for reliable-condition lasers. In most cases, they are doped with both trivalent exceptional 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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the higher-point out life time.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
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 employed to reliably determine the optimum crystal dimensions, doping density And perhaps values of further 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。
It is obvious that different applications lead to pretty distinct specifications on laser gain media. For that reason, a wide variety of various crystals are utilized, and earning the best alternative is essential for setting up lasers with the best possible effectiveness.
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 should have a higher transparency (minimal absorption and scattering) from the wavelength check here locations of pump and laser radiation, and good optical homogeneity. To some extent, this depends on the standard of the fabric, based on aspects of your fabrication procedure.
There is certainly a wide array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline buildings. Some essential groups of crystals are:
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。
