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。

Also, some adaptability is misplaced in experiments if one can not try out absorbers with diverse 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：

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。

g. a thin disk. As A different example, Q-switched lasers access a higher populace density from the higher laser degree and so are therefore a lot more sensitive to quenching effects and Vitality transfer processes; as a result, a decreased doping density is commonly suitable for these devices. For high-energy lasers, reduce doping densities are sometimes accustomed to limit the density of heat technology, Even though thin-disk lasers function best with highly doped crystals. Many laser products never get to the comprehensive effectiveness potential for the reason that these kinds of specifics haven't been effectively labored out.

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。

It is clear that different apps result in incredibly unique necessities on laser achieve media. Due to this, a broad assortment of different crystals are used, and making the proper choice is important for setting up lasers with optimum overall performance.

Diverse crystalline supplies are really diverse concerning their hardness together with other properties, which decide with which methods And just how conveniently they can be Lower and polished with high quality.

The medium ought to have a substantial transparency (reduced absorption and scattering) during click here the wavelength areas of pump and laser radiation, and good optical homogeneity. To some extent, this relies on the quality of the fabric, determined by information of the fabrication approach.

With That idea, just one won't will need a further saturable absorber crystal, to ensure a single might make much more compact Q-switched laser setups with lower interior parasitic losses. Having said that, undesired Uncomfortable side effects may additionally happen, which include acquiring unwelcome valence states on the involved ions or Strength transfers.

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。
