These ions help the crystal to amplify mild in the laser wavelength by using stimulated emission, when Electricity is supplied on the crystal by way of absorption of pump light (�?optical pumping
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
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。
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 attain the next population density from the upper laser degree and therefore are hence a lot more delicate to quenching consequences and Power transfer processes; thus, a lower doping density is usually appropriate for these products. For top-ability lasers, lower doping densities tend to be used to Restrict the density of warmth era, Though skinny-disk lasers function very best with extremely doped crystals. Many laser products and solutions tend not to reach the complete efficiency prospective since this kind of details haven't been appropriately worked out.
Laser modeling and simulation can be employed to reliably establish the optimum crystal Proportions, doping density more info and possibly values of more parameters.
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 unique purposes produce very different specifications on laser acquire media. Because of this, a broad range of various crystals are made use of, and building the proper choice is essential for constructing lasers with the best possible performance.
Distinctive crystalline resources are incredibly different relating to their hardness as well as other Attributes, which decide with which methods And the way conveniently they can be Slice and polished with top quality.
For many motives, composite crystals are becoming well-known. These have a spatially different chemical composition and can be built with Exclusive shapes.
With That idea, one particular won't will need a further saturable absorber crystal, making sure that just one may possibly make far more compact Q-switched laser setups with reduced internal parasitic losses. Nevertheless, unwelcome Unintended effects may take place, for example acquiring undesirable valence states on the included ions or Electrical power transfers.
