The most typical laser-Lively rare earth ions and host media along with some usual emission wavelengths are demonstrated in the next table:

Laser crystals are optical crystals �?usually one crystals (monocrystalline optical components) �?that are made use of as achieve media for solid-condition lasers. Usually, They're doped with both trivalent scarce earth ions or transition metal 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：

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。

Certainly, it is vitally fascinating that a presented crystal good quality is made regularly, Even though different laser models may have a different sensitivity to materials parameters.

The most achievable doping focus can depend strongly over the host content and its fabrication method.

The host crystal is considerably more than simply a method to fix the laser-active ions at specified positions in House. Numerous Homes with the host product are important:

蓝宝�?柱面�?球罩 偏振�?棱镜 红外光学元件 反射�?光学窗口 非球面镜 波片 分光�?制造能力

For quasi-a few-stage laser acquire media and click here even three-amount obtain media, 1 normally should limit the duration to a price which is far too quick for economical pump absorption, as reabsorption results would otherwise spoil the effectiveness. For side pumping, added considerations arrive into Enjoy; In addition to productive pump absorption, it is important to get an acceptable spatial condition of the acquire profile.

Distinct crystalline resources are extremely distinctive regarding their hardness and other Homes, which determine with which procedures and how simply they may be Reduce and polished with high quality.

For different factors, composite crystals are becoming preferred. These Use a spatially various chemical composition and will be designed with Particular shapes.

It could be oriented for in the vicinity of perpendicular incidence of the laser beam, or at Brewster's angle. It can be fixed in some reliable mount which also functions for a warmth sink. Much larger crystals tend to be useful for facet pumping e.g. with superior-electric 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。
