These tables include only the most common host crystals; many Other folks exist, that happen to be a lot less often utilised.

These ions enable the crystal to amplify mild with the laser wavelength by means of stimulated emission, when Electricity is provided to the crystal through absorption of pump gentle (�?optical pumping

激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

Certainly, it is very attractive that a provided crystal excellent is produced constantly, Whilst various laser types might have a different sensitivity to content parameters.

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-3-stage laser acquire media or perhaps three-level acquire media, one particular often needs to limit the length to a price which can be way too short for economical pump absorption, as reabsorption outcomes would normally spoil the efficiency. For facet pumping, extra things to consider click here come into Engage in; Moreover productive pump absorption, it is necessary to get an acceptable spatial condition in the gain profile.

The medium must have a significant transparency (small absorption and scattering) during the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this is dependent upon the quality of the fabric, determined by facts of your fabrication process.

With that concept, 1 does not need an extra saturable absorber crystal, to ensure that one might make much more compact Q-switched laser setups with lessen inside parasitic losses. On the other hand, unwanted Unwanted side effects could also come about, for instance getting unwanted valence states in the included ions or Strength 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。
