The most common laser-Energetic exceptional earth ions and host media along with some regular emission wavelengths are demonstrated in the next desk:

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 �?normally one crystals (monocrystalline optical elements) �?which can be used as achieve media for solid-condition lasers. Most often, They may be 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：

A superior surface good quality is certainly essential. Specs of surface area flatness in many cases are much better than . This can help to avoid each scattering losses and wavefront distortions which could degrade the laser's beam excellent. On top of that, scratch and dig technical specs

探索激光晶体的领域，可以让我们看到科学和技术相结合的奇迹，为我们带来了令人难以置信的进步。这些激光晶体，每一种都在组成和特性上独具匠心，是推动现代世界众多应用的动力。

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。

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

For quasi-three-degree laser check here gain media or maybe 3-level get media, a single often should Restrict the length to a price which is also shorter for effective pump absorption, as reabsorption outcomes would if not spoil the functionality. For side pumping, added criteria occur into Perform; Moreover efficient pump absorption, it is necessary to obtain a suitable spatial shape on the get profile.

The medium should have a superior transparency (lower absorption and scattering) inside the wavelength locations of pump and laser radiation, and great optical homogeneity. To some extent, this depends on the caliber of the fabric, determined by aspects on the fabrication process.

With that concept, a single will not want an extra saturable absorber crystal, in order that a single could make much more compact Q-switched laser setups with lower interior parasitic losses. Having said that, undesired Uncomfortable side effects may take place, like obtaining unwelcome valence states in the involved ions or Electricity transfers.

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。
