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 �?ordinarily one crystals (monocrystalline optical materials) �?that happen to be utilized as acquire media for solid-point out lasers. Normally, They are really doped with either trivalent scarce earth ions or transition metal ions.
Additionally, some versatility is misplaced in experiments if a person are not able to Check out absorbers with distinct thickness or doping focus, for instance, with out exchanging the laser crystal by itself.
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 floor high quality is certainly significant. Specs of surface flatness in many cases are a lot better than . This helps to stay away from equally scattering losses and wavefront distortions which often can degrade the laser's beam excellent. Additionally, 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。
The host crystal is way more than just a way to fix the laser-Energetic ions at certain positions in Area. A more info variety of Attributes from the host content are crucial:
热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。
These surfaces which happen to be passed from the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.
Distinct crystalline materials are certainly distinct about their hardness along with other Attributes, which decide with which solutions and how conveniently they can be Lower and polished with high quality.
GWU-Lasertechnik has much more than thirty years of expertise in distributing laser crystals. Decide on GWU to get pleasure from our large awareness As well as in-subject practical experience!
With that concept, 1 will not want an extra saturable absorber crystal, so that one may perhaps make extra compact Q-switched laser setups with lessen inside parasitic losses. Nonetheless, unwanted Unwanted side effects could also manifest, for example obtaining undesired valence states from the associated ions or Vitality 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。
