Laser crystals are optical crystals �?usually solitary crystals (monocrystalline optical materials) �?that are utilised as achieve media for stable-point out lasers. Usually, They're doped with possibly trivalent exceptional earth ions or changeover steel ions.
Additionally, some versatility is missing in experiments if one particular can not Check out absorbers with diverse thickness or doping focus, one example is, without having exchanging the laser crystal by 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：
GWU delivers all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) having a broad number of requirements. In addition to the very well-set up products, impressive crystals with exceptional Attributes like Yb:CALGO can open up new horizons for demanding laser apps. Irrespective of irrespective of whether specific items for R & D applications are needed or Price tag-efficient numbers in smaller, medium or substantial batches with in-time delivery with the creation line are desired: GWU’s devoted support helps to discover the ideal core components in your application.
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。
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
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 unique purposes result in quite unique prerequisites on laser gain media. Because of this, a get more info wide vary of various crystals are made use of, and producing the best preference is essential for developing lasers with the best possible 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。
For different motives, composite crystals are getting to be well-liked. These Possess a spatially varying chemical composition and may be created with Specific designs.
With That idea, one won't need an extra saturable absorber crystal, making sure that a person may make much more compact Q-switched laser setups with lessen internal parasitic losses. Even so, undesirable Uncomfortable side effects may additionally manifest, such as getting undesired valence states with the included ions or Strength transfers.
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。
