These tables incorporate only the most typical host crystals; several others exist, that are less often applied.

These ions enable the crystal to amplify gentle within the laser wavelength by means of stimulated emission, when Vitality is supplied into the crystal through absorption of pump light-weight (�?optical pumping

Laser crystals are optical crystals �?normally solitary crystals (monocrystalline optical materials) �?which might be used as attain media for solid-point out lasers. Generally, These are doped with both trivalent unusual earth ions or transition steel 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：

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

活性离子在激光晶体内发生的能量跃迁对激光操作至关重要。大多数激光操作都是通过四能级系统原理进行的，确保连续操作并防止浪费的非辐射衰变。

g. a skinny disk. As An additional case in point, Q-switched lasers achieve a higher populace density within the higher laser level and so are therefore additional sensitive to quenching outcomes and Power transfer processes; hence, a lower doping density is often appropriate for these products. For top-electrical power lasers, decreased doping densities tend to be accustomed read more to Restrict the density of warmth era, Though slender-disk lasers work very best with hugely doped crystals. Many laser goods don't reach the total performance probable for the reason that this sort of aspects have not been thoroughly 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。

For quasi-a few-stage laser get media or perhaps three-amount get media, a single frequently must limit the size to a worth that is too small for efficient pump absorption, as reabsorption outcomes would if not spoil the effectiveness. For side pumping, extra issues arrive into Engage in; Other than economical pump absorption, it is crucial to obtain a suitable spatial form of the gain profile.

GWU-Lasertechnik has in excess of thirty many years of practical experience in distributing laser crystals. Choose GWU to take advantage of our huge awareness As well as in-field encounter!

You can find a wide array of crystalline media, that may be grouped according to important atomic constituents and crystalline constructions. Some significant teams of crystals are:

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。
