Unique crystalline components are very diverse concerning their hardness and also other Qualities, which ascertain with which techniques And just how easily they are often Slice 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 changeover 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。

The most achievable doping focus can depend strongly to the host materials and its fabrication system.

g. a thin disk. As One more example, Q-switched lasers achieve the next population density while in the higher laser level and so are hence much more sensitive to quenching outcomes and Electricity transfer processes; thus, a lower doping density is usually suitable for these equipment. For high-electrical power lasers, decreased doping densities tend to be accustomed to Restrict the density of warmth technology, although skinny-disk lasers operate most effective with highly doped crystals. Numerous laser merchandise will not get to the full overall performance prospective mainly because these types of details have not been correctly worked out.

A substantial damage threshold with regard to pulse fluence or peak intensity is Laser Crystal often essential for prime-energy 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：

It might be oriented for in close proximity to perpendicular incidence of your laser beam, or at Brewster's angle. It can be fixed in some strong mount which also acts like a heat sink. More substantial crystals usually are useful for facet pumping e.g. with significant-ability diode bars.

The commonest laser-Lively unusual earth ions and host media together with some common emission wavelengths are shown in the subsequent table:

People surfaces that are handed from the laser beam are Commonly either oriented at Brewster's angle or have an anti-reflection coating.

Certainly, it is extremely fascinating that a specified crystal high quality is made continually, although distinct laser types might have another sensitivity to material parameters.

There is certainly a wide array of crystalline media, which may be grouped in accordance to special atomic constituents and crystalline buildings. Some significant teams of crystals are:

Laser crystals are optical crystals �?typically solitary crystals (monocrystalline optical supplies) �?that are made use of as get media for reliable-state lasers. Most often, These are doped with possibly trivalent unusual earth ions or changeover metal ions.

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。
