These tables contain only the most typical host crystals; quite a few Other people exist, which might be much less usually applied.

Laser crystals are optical crystals �?commonly one crystals (monocrystalline optical components) �?that are employed as get media for reliable-condition lasers. In most cases, They're doped with both trivalent unusual earth ions or changeover metallic ions.
Additionally, some adaptability is missing in experiments if one cannot Check out absorbers with distinct thickness or doping focus, by way of example, without the need of exchanging the laser crystal itself.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions in addition to the upper-point out life span.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Of course, it is rather attractive that a provided crystal quality is generated consistently, Despite the fact that distinctive laser patterns may have another sensitivity to materials 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。
The host crystal is way more than just a method to fix the laser-Lively ions at particular positions in House. Several Attributes in the host product are essential:
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。

The medium must have a higher transparency (small absorption and scattering) during the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this is dependent upon the caliber of the fabric, based on information with the fabrication system.
With That idea, just one will not require yet another saturable absorber crystal, to ensure 1 may make much more compact Q-switched laser setups with lower interior parasitic losses. On the other hand, undesirable Negative effects may additionally come about, for click here instance getting undesirable valence states with the concerned ions or Electricity 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。
