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。
Which geometry, dopant and doping concentration of your obtain medium are most useful rely on various aspects. The out there pump source (style of laser diode or lamp) as well as the envisaged pumping arrangement are crucial elements, but the fabric alone also has some impact. For example, titanium–sapphire lasers must be pumped with superior intensities, for which the form of a transversely cooled rod, operated with rather tiny pump and laser beam diameter, is much more correct than e.
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 skinny disk. As A different instance, Q-switched lasers arrive at a higher populace density inside the upper laser level and they are therefore much more sensitive to quenching outcomes and Vitality transfer procedures; as a result, a reduce doping density is commonly appropriate for these devices. For prime-electrical power lasers, reduce doping densities are sometimes used to Restrict the density of warmth generation, Whilst thin-disk lasers operate ideal with very doped crystals. Numerous laser products and solutions don't get to the total efficiency opportunity due to the fact this kind of specifics have not been thoroughly 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 apparent that diverse applications cause extremely distinctive prerequisites on laser attain media. This is why, a broad variety of different crystals are made use of, and building the best option is important for setting up lasers with optimum effectiveness.

The medium should have a large transparency (minimal absorption and scattering) while in the here wavelength areas of pump and laser radiation, and fantastic optical homogeneity. To some extent, this relies on the standard of the material, determined by details of the fabrication method.
You can find a wide range of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline structures. Some crucial groups of crystals are:
