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 from the gain medium are most advantageous count on various components. The readily available pump supply (variety of laser diode or lamp) and the envisaged pumping arrangement are crucial components, but the material alone also has some affect. For instance, titanium–sapphire lasers have to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with comparatively modest pump and laser beam diameter, is a lot more acceptable 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。
Needless to say, it is extremely desirable that a given crystal high-quality is generated continually, Despite the fact that various laser designs may have a special sensitivity to substance parameters.
g. a skinny disk. As An additional illustration, Q-switched lasers reach a better inhabitants density within the upper laser stage and they are consequently much more sensitive to quenching consequences and energy transfer processes; as a result, a decrease doping density is frequently suitable for more info these equipment. For top-power lasers, reduce doping densities are frequently accustomed to limit the density of heat generation, Though skinny-disk lasers perform greatest with hugely doped crystals. A lot of laser items usually do not reach the comprehensive general performance opportunity mainly because these kinds of particulars 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。

It is obvious that different programs produce pretty distinctive necessities on laser achieve media. Because of this, a broad assortment of different crystals are employed, and generating the best selection is important for constructing lasers with optimum effectiveness.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
GWU-Lasertechnik has much more than 30 many years of knowledge in distributing laser crystals. Opt for GWU to reap the benefits of our broad information and in-area expertise!
It may be oriented for around perpendicular incidence on the laser beam, or at Brewster's angle. It might be preset in some solid mount which also acts as a heat sink. More substantial crystals are frequently employed for aspect pumping e.g. with large-electric power 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。
