Unique crystalline elements are extremely various about their hardness together with other Homes, which figure out with which methods And exactly how quickly they can be Slash and polished with good quality.
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。
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the higher-point out life span.
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。
For quasi-3-amount laser gain media as well as three-amount achieve media, one particular generally really should limit the size to a worth that is way too shorter for productive pump absorption, as reabsorption outcomes would or else spoil the general performance. For aspect pumping, extra criteria occur into Perform; Moreover efficient pump absorption, it's important to obtain an appropriate spatial form from the obtain profile.
g. a thin disk. As Yet another instance, Q-switched lasers attain a higher populace density inside the upper laser degree and they are for that reason a lot more sensitive to quenching outcomes and energy transfer procedures; as a result, a lower doping density is commonly appropriate for these devices. For top-electrical power lasers, lower doping densities are sometimes used to limit the density of heat generation, although slender-disk lasers get the job done finest with highly doped crystals. Numerous laser merchandise do not reach the entire general performance likely mainly because these particulars have not been thoroughly worked out.
GWU-Lasertechnik has a lot more than thirty yrs of knowledge in distributing laser crystals. Decide on GWU to take advantage of our vast knowledge As well as in-area expertise!
A substantial harm threshold concerning pulse fluence or peak intensity is often important for top-Power amplifiers.
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：

These tables consist of only the most common host crystals; numerous Some others exist, that happen to be less usually utilized.
Below you can post questions and reviews. So far as they get approved because of the creator, they can look previously mentioned this paragraph together with the author’s solution. The author will make a decision on acceptance determined by specified requirements. Primarily, the issue must be of sufficiently wide interest.
A few laser crystal components are already shown where some saturable absorber material is integrated for passive Q switching of a laser.
For various explanations, composite crystals have become preferred. These Have got a spatially various chemical composition and may be designed with special styles.
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。
With That idea, one particular would not want an additional saturable absorber crystal, in order that one may make much more compact Q-switched laser setups with decreased inner parasitic losses. Having said that, undesirable Unwanted side effects may come about, for example acquiring undesired valence states of the associated ions or Vitality transfers.

Laser crystals are optical crystals �?generally one crystals (monocrystalline optical supplies) �?which happen to here be employed as achieve media for sound-condition lasers. In most cases, They may be doped with both trivalent uncommon earth ions or transition metal ions.
