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 �?commonly single crystals (monocrystalline optical materials) �?which are utilised as gain media for sound-condition lasers. In most cases, They're doped with either trivalent uncommon earth ions or transition 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。

Which geometry, dopant and doping concentration of your get medium are most beneficial depend upon numerous aspects. The accessible pump resource (style of laser diode or lamp) plus the envisaged pumping arrangement are essential components, but the fabric itself also has some affect. For instance, titanium–sapphire lasers must be pumped with large intensities, for which the shape of the transversely cooled rod, operated with reasonably little pump and laser beam diameter, is more ideal 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。

Of course, check here it is very attractive that a specified crystal high-quality is manufactured continuously, While distinct laser styles might have a unique sensitivity to content parameters.

The most attainable doping concentration can rely strongly on the host substance and its fabrication technique.

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。

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

For quasi-three-degree laser attain media and even a few-stage obtain media, one generally should Restrict the size to a worth that is far too brief for successful pump absorption, as reabsorption effects would normally spoil the overall performance. For aspect pumping, supplemental concerns arrive into Enjoy; Aside from economical pump absorption, it's important to obtain an appropriate spatial form with the achieve profile.

For numerous factors, composite crystals are becoming preferred. These Use a spatially varying chemical composition and will be designed with Particular styles.

It may be oriented for close to perpendicular incidence in the laser beam, or at Brewster's angle. It may be set in some strong mount which also functions to be a warmth sink. More substantial crystals are frequently utilized for side pumping e.g. with high-ability 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。
