The most typical laser-Energetic scarce earth ions and host media along with some usual emission wavelengths are proven in the following desk:
These ions permit the crystal to amplify light-weight for the laser wavelength through stimulated emission, when Electricity is equipped into the crystal via absorption of pump light (�?optical pumping
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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：
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。
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。
For quasi-three-level laser gain media as well as 3-degree obtain media, just one generally really should Restrict the length to a value which can be way too quick for productive pump absorption, as reabsorption outcomes would in any other case spoil the general performance. For side pumping, extra factors appear into Perform; Moreover effective pump absorption, it is important to acquire an appropriate spatial shape of the attain profile.
Various crystalline supplies are very distinctive relating to their hardness and various Homes, which identify with which procedures And the way very easily they may be cut and polished with good quality.
GWU-Lasertechnik has much more than 30 decades Laser Crystal of expertise in distributing laser crystals. Pick out GWU to gain from our large awareness and in-area practical experience!
It could be oriented for around perpendicular incidence of your laser beam, or at Brewster's angle. It might be fastened in a few good mount which also functions as being a warmth sink. Larger crystals are often used for side pumping e.g. with superior-electric power diode bars.
