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。

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：

A significant surface area high-quality is naturally essential. Specs of area flatness in many cases are better than . This will help in order to avoid both of those scattering losses and wavefront distortions which might degrade the laser's beam high quality. Moreover, scratch and dig requirements

g. a thin disk. As A further illustration, Q-switched lasers achieve a higher populace density while in the upper laser degree and are hence more delicate to quenching results and Power transfer processes; therefore, a lower doping density is often appropriate for these products. For prime-ability lasers, decrease doping densities are sometimes utilized to Restrict the density of heat generation, Despite the fact that skinny-disk lasers do the job finest with very doped crystals. A lot of laser merchandise don't get to the full efficiency opportunity since these types of specifics have not been adequately worked 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。

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-3-amount laser acquire media or perhaps three-stage attain media, a single often has to limit the more info duration to a price which can be too brief for efficient pump absorption, as reabsorption consequences would usually spoil the functionality. For side pumping, more factors come into Engage in; besides economical pump absorption, it's important to get a suitable spatial shape with the gain profile.

The medium should have a substantial transparency (very low absorption and scattering) while in the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this depends upon the standard of the fabric, determined by specifics of the fabrication process.

Working with our advertising deal, you may Exhibit your brand, even further underneath your solution description, and these will been observed by several photonics specialists.
