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。

In addition, some versatility is dropped in experiments if 1 are not able to try out absorbers with distinctive thickness or doping concentration, for example, without the need of 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。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

g. a skinny disk. As One more case in point, Q-switched lasers achieve the next population density while in the higher laser level and so are therefore a lot more delicate to quenching consequences and Vitality transfer procedures; hence, a reduce doping density is usually appropriate for these units. For prime-electric power lasers, lessen doping densities are often used to Restrict the density of warmth era, While slim-disk lasers do the job best with highly doped crystals. Many laser solutions will not reach the total efficiency possible because these types of information have not been thoroughly worked out.

The host crystal is a lot more than simply a method to repair the laser-active ions at specific positions in Place. Numerous Homes with the host product are important:

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。

The medium ought to have a significant transparency (minimal absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, based on specifics check here of the fabrication approach.

Applying our promoting package deal, you are able to Screen your brand, additional underneath your products description, and these will been witnessed by several photonics specialists.

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。
