The commonest laser-Energetic exceptional earth ions and host media together with some typical emission wavelengths are proven in the following table:
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?normally solitary crystals (monocrystalline optical materials) �?which might be used as obtain media for reliable-point out lasers. Typically, They may be doped with possibly trivalent rare earth ions or changeover metallic ions.
On top of that, some overall flexibility is dropped in experiments if a single simply cannot Check out absorbers with different thickness or doping focus, for example, with out exchanging the laser crystal itself.
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。
A high surface top quality is not surprisingly vital. Specifications of surface flatness are frequently much better than . This allows to avoid both scattering losses and wavefront distortions which may degrade the laser's beam high quality. Additionally, scratch and dig specifications
The most attainable doping concentration can rely strongly over the host content and its fabrication method.
Laser modeling and simulation can be utilized to reliably identify the optimum crystal Proportions, doping density and possibly values of added parameters.
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。

Different crystalline materials are very diverse relating to their hardness and other Homes, which establish with which techniques And just how effortlessly they are often Reduce and polished with good quality.
For numerous motives, composite crystals have gotten common. These Have got a spatially varying chemical composition and might be manufactured with Distinctive styles.
It could be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It could be fastened in certain stable mount which also functions as a heat sink. Much larger website crystals are generally used for side pumping e.g. with significant-energy diode bars.
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。
