These ions enable the crystal to amplify light-weight for the laser wavelength by means of stimulated emission, when Strength is supplied into the crystal by means of absorption of pump mild (�?optical pumping
Laser crystals are optical crystals �?normally one crystals (monocrystalline optical components) �?which might be utilised as acquire media for reliable-point out lasers. Usually, They're doped with both trivalent scarce earth ions or transition steel ions.
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。
This is easy to carry out: just find the lock icon before the URL within the tackle bar and drag that to the bookmark toolbar While using the mouse. In case you discover the bookmark entry as well extensive, you'll be able to suitable-click it to edit the text, e.g. employing "RP Enc" as an alternative to "RP Photonics Encyclopedia".
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 the best possible crystal dimensions, doping density and possibly values of further parameters.
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。
Individuals surfaces that happen to be passed by the laser beam Laser Crystal are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.
Diverse crystalline supplies are very unique about their hardness together with other Qualities, which identify with which strategies And exactly how effortlessly they are often cut and polished with high quality.
For numerous factors, composite crystals are becoming popular. These Have got a spatially different chemical composition and may be produced with special styles.
There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some essential groups of crystals are:
人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
