These tables incorporate only the commonest host crystals; several Many others exist, which can be fewer usually used.
Listed here you may post inquiries and comments. In terms of they get accepted through the writer, they can appear over this paragraph together with the creator’s solution. The author will decide on acceptance according to particular criteria. Essentially, The difficulty needs to be of adequately broad desire.
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。
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
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 provides all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) that has a wide a number of specifications. Apart from the properly-recognized elements, ground breaking crystals with outstanding Houses like Yb:CALGO can open new horizons for demanding laser applications. It doesn't matter whether unique items for R & D reasons are required or Charge-productive quantities in smaller, medium or significant batches with in-time shipping and delivery for the creation line are needed: GWU’s committed service helps you to find the finest core parts on your software.
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 thin disk. As One more example, Q-switched lasers arrive at a better population density while in the higher laser amount and therefore are hence a lot more delicate to quenching outcomes and Electrical power transfer processes; as a result, a decrease doping density is commonly suitable for these equipment. For high-electricity lasers, decreased doping densities are often used to limit the density website of warmth technology, Whilst slender-disk lasers do the job most effective with really doped crystals. Quite a few laser merchandise don't reach the full overall performance possible because these kinds of facts have not 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。

For quasi-a few-stage laser acquire media or simply a few-stage achieve media, a single often really should limit the length to a worth that's as well shorter for productive pump absorption, as reabsorption effects would otherwise spoil the general performance. For side pumping, more concerns appear into Participate in; In addition to productive pump absorption, it can be crucial to obtain a suitable spatial shape in the achieve profile.
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 benefit from our broad information and in-field encounter!
There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some critical teams of crystals are:
