The commonest laser-Energetic exceptional earth ions and host media together with some normal emission wavelengths are shown in the subsequent table:

These ions permit the crystal to amplify light in the laser wavelength via stimulated emission, when energy is equipped into the crystal via absorption of pump mild (�?optical pumping

Laser crystals are optical crystals �?usually single crystals (monocrystalline optical components) �?which happen to be employed as achieve media for solid-condition lasers. In most cases, they are doped with either trivalent uncommon earth ions or changeover metal ions.

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：

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。

Of course, it is vitally appealing that a given crystal quality is made continuously, While distinct laser designs may have a distinct sensitivity to content parameters.

g. a skinny disk. As A further case in point, Q-switched lasers arrive at a better inhabitants density in the upper laser degree and are for that reason a lot more sensitive to quenching outcomes and Strength transfer processes; therefore, a lower doping density is commonly suitable for these products. For high-electrical power lasers, decreased doping densities will often be accustomed to Restrict the density of heat technology, Even though slim-disk lasers get the job done ideal with really Laser Crystal doped crystals. Quite a few laser merchandise never reach the comprehensive overall performance possible since these specifics haven't been correctly worked 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。

It is obvious that distinctive apps bring about extremely different prerequisites on laser attain media. For this reason, a broad selection of different crystals are utilised, and earning the appropriate decision is important for setting up lasers with the best possible overall performance.

For several motives, composite crystals have gotten common. These Have a very spatially various chemical composition and can be created with Particular shapes.

It may be oriented for close to perpendicular incidence with the laser beam, or at Brewster's angle. It might be mounted in some strong mount which also acts as being a heat sink. More substantial crystals tend to be utilized for facet pumping e.g. with significant-power diode bars.

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。
