The commonest laser-Energetic rare earth ions and host media along with some normal emission wavelengths are shown in the following table:
These ions help the crystal to amplify light at the laser wavelength by means of stimulated emission, when Electrical power is provided to your crystal by means of absorption of pump mild (�?optical pumping
芯飞睿所有的服务和支持都立足于使我们的客人工作的更加高效，更有价值。
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 focus from the attain medium are most useful depend on many elements. The out there pump source (style of laser diode or lamp) and also the envisaged pumping arrangement are very important elements, but the material by itself also has some impact. One example is, titanium–sapphire lasers need to be pumped with substantial intensities, for which the shape of the transversely cooled rod, operated with fairly smaller pump and laser beam diameter, is much more correct than e.
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。
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。
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。
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。
It is apparent that various purposes bring about extremely distinctive specifications on laser achieve media. Because of this, a wide variety of different crystals are made use more info of, and generating the ideal option is important for setting up lasers with the best possible functionality.

In 2017, we designed the planet’s largest Ti∶sapphire crystal (Φ235 mm), which supported the 10 PW laser output of Shanghai Superintense Ultrafast Laser Facility. The development of Yb and Tm doped GdScO3 laser crystals with incredibly broad emission spectra drives the event of laser diode pumped ultrafast good-condition lasers. With the increase in pulse Vitality, peak ability, and repetition level of reliable-state lasers, laser crystals will develop towards larger dimensions, bigger crystal high-quality, and controllable important effectiveness.
It could be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It can be mounted in a few reliable mount which also functions being a warmth sink. Much larger crystals tend to be useful for facet pumping e.g. with significant-electric 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。
