These tables comprise only the most common host crystals; several Some others exist, which can be considerably less routinely used.
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。
Laser crystals are optical crystals �?commonly solitary crystals (monocrystalline optical resources) �?which might be made use of as gain media for strong-state lasers. Generally, They're doped with both trivalent unusual earth ions or transition steel ions.
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 delivers all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so forth.) that has a wide selection of technical specs. Apart from the properly-recognized supplies, modern crystals with remarkable Houses like Yb:CALGO can open up new horizons for demanding laser purposes. Regardless of no matter whether unique pieces for R & D reasons are expected or cost-effective quantities in smaller, medium or significant batches with in-time supply with the manufacturing line are necessary: GWU’s focused services helps you to find the greatest Main parts on your application.
A large area excellent is certainly crucial. Specifications of surface area flatness are sometimes much better than . This aids to prevent each scattering losses and wavefront distortions which may degrade the laser's beam top quality. Furthermore, scratch and dig technical specs
g. a skinny disk. As another example, Q-switched lasers get to a better population density inside the higher laser stage and they are therefore far more delicate to quenching effects and Vitality transfer processes; consequently, a reduced doping density is usually appropriate for these devices. For high-ability lasers, reduce doping densities are frequently used to limit the density of heat generation, Despite the fact that thin-disk lasers work ideal with really doped crystals. Several laser products and solutions do not get to the full performance prospective due to the fact these facts have not been appropriately labored out.
The host crystal is a great deal more than just a means to fix the laser-active ions at particular positions in House. A number of properties from the host substance are very important:
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 programs lead to incredibly various needs on laser achieve media. For that reason, a broad assortment of various crystals are utilized, and generating the right decision is important for developing lasers with optimum efficiency.
Unique crystalline products are very various concerning their hardness together with other Qualities, which determine with which methods And exactly how easily they can be Lower and polished with good quality.
For various explanations, composite crystals have become well known. These have a spatially various chemical composition and will be produced with Specific styles.
With that concept, just one does not need to have yet another saturable absorber crystal, to ensure that check here one particular may well make extra compact Q-switched laser setups with reduced internal parasitic losses. Having said that, unwanted Unwanted side effects can also occur, for instance obtaining undesirable valence states in the concerned ions or Vitality 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。
