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。
Which geometry, dopant and doping concentration of the acquire medium are most advantageous depend on a number of elements. The accessible pump source (variety of laser diode or lamp) and the envisaged pumping arrangement are crucial things, but the fabric itself also has some impact. One example is, titanium–sapphire lasers should be pumped with large intensities, for which the shape of a transversely cooled rod, operated with fairly small pump and laser beam diameter, is much more suitable than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
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 An additional example, Q-switched lasers get to a higher population density from the upper laser degree and so are hence a lot more delicate to quenching outcomes and energy transfer processes; as a result, a reduce doping density is usually suitable for these products. For top-ability lasers, reduced doping densities in many cases are utilized to Restrict the density of heat era, Though skinny-disk lasers perform ideal with very doped crystals. Several laser items usually do not reach the entire effectiveness likely due to the fact this sort of particulars haven't 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。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is apparent that distinctive applications lead to extremely various needs on laser achieve media. This is why, a wide selection of various crystals are applied, and building the appropriate alternative is essential for constructing lasers with the best possible general performance.
Distinctive crystalline elements are incredibly different relating to their hardness as well as other Attributes, which decide with which solutions And the way quickly they are often Slash and polished with good quality.
For a variety of reasons, composite crystals have become common. These have a spatially varying chemical composition and will be designed with Particular styles.
With That idea, one particular does not have to have an extra saturable absorber crystal, to make sure that one particular may possibly make much more compact Q-switched laser setups with decreased internal parasitic losses. However, undesired Negative effects may manifest, for example obtaining undesired Laser Crystal valence states in the associated ions or Strength transfers.
