The most typical laser-active rare earth ions and host media together with some usual emission wavelengths are revealed in the following 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 �?commonly solitary crystals (monocrystalline optical resources) �?which are made use of as acquire media for reliable-condition lasers. In most cases, They can be doped with possibly trivalent rare earth ions or transition metallic 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：

Obviously, it is extremely desirable that a given crystal quality is manufactured continuously, While diverse laser patterns may have a unique sensitivity to content parameters.
The most achievable doping focus can depend strongly over the host materials and its fabrication process.
The host crystal is way more than just a means to fix the laser-Energetic ions at sure positions in space. A variety of properties in the host substance are crucial:
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 clear that different applications bring about quite unique demands on laser get media. Due to this, a wide array of different crystals are employed, and producing the correct alternative is important for constructing lasers with the best possible general performance.
Various crystalline products are quite various regarding their hardness as well as other Houses, which figure out with which methods And the way quickly they are often Minimize and polished with high quality.
GWU-Lasertechnik has a lot read more more than thirty several years of practical experience in distributing laser crystals. Opt for GWU to gain from our vast knowledge and in-industry experience!
With That idea, just one would not have to have yet another saturable absorber crystal, to make sure that a person might make a lot more compact Q-switched laser setups with reduce internal parasitic losses. However, unwelcome Unintended effects may arise, like getting undesirable valence states of the concerned ions or Electrical power transfers.
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。
