These tables incorporate only the most typical host crystals; numerous Other people exist, which can be less commonly utilized.
Here you may submit queries and comments. So far as they get recognized via the writer, they are going to look over this paragraph along with the author’s remedy. The writer will make a decision on acceptance depending on selected conditions. Basically, The problem needs to be of sufficiently broad interest.
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。
On top of that, some flexibility is lost in experiments if 1 can't try out absorbers with distinctive thickness or doping concentration, such as, with out 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 presents all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) by using a broad assortment of requirements. Aside from the properly-recognized elements, ground breaking crystals with superb Attributes like Yb:CALGO can open up new horizons for demanding laser apps. Despite irrespective of whether individual items for R & D reasons are needed or Price-efficient quantities in smaller, medium or massive batches with in-time shipping and delivery for the production line are necessary: GWU’s dedicated service really helps to discover the very best Main components for the software.
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 another instance, Q-switched lasers get to an increased inhabitants density in the upper laser degree and therefore are for that reason additional sensitive to quenching outcomes and Electricity transfer procedures; hence, a lower doping density is commonly here appropriate for these units. For prime-electricity lasers, decreased doping densities in many cases are utilized to Restrict the density of heat generation, Though skinny-disk lasers function very best with highly doped crystals. Many laser products never get to the whole effectiveness likely due to the fact this sort of particulars haven't 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。
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。
For quasi-three-degree laser achieve media or simply three-level obtain media, just one frequently has to limit the size to a price which happens to be also short for productive pump absorption, as reabsorption effects would usually spoil the performance. For facet pumping, additional concerns arrive into Perform; Apart from productive pump absorption, it is crucial to get an appropriate spatial form in the obtain profile.

For several explanations, composite crystals are becoming well-known. These Use a spatially different chemical composition and will be produced with Particular designs.
There's an array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline buildings. Some essential groups of crystals are:
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。
