Laser crystals are optical crystals �?typically single crystals (monocrystalline optical resources) �?that are utilised as achieve media for solid-point out lasers. Normally, They can be doped with possibly trivalent uncommon earth ions or changeover metal 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。
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
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。
激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。
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。
The host crystal is considerably more than simply a way to repair the laser-Energetic ions at sure positions in Room. A number of Houses of the host product are crucial:
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
For quasi-three-level laser obtain media as well as website a few-amount attain media, 1 usually should Restrict the size to a price and that is much too shorter for efficient pump absorption, as reabsorption effects would or else spoil the efficiency. For aspect pumping, further issues appear into Engage in; Aside from productive pump absorption, it is crucial to get an appropriate spatial shape of 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 high transparency (small absorption and scattering) from the wavelength regions of pump and laser radiation, and great optical homogeneity. To some extent, this is determined by the quality of the material, based on information in the fabrication approach.
Utilizing our advertising package, you'll be able to Exhibit your symbol, even more under your solution description, and these will been noticed by many photonics gurus.
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。
