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。

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。

In addition, some adaptability is dropped in experiments if 1 cannot Check out absorbers with distinct thickness or doping concentration, such as, with no exchanging the laser crystal itself.

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and also the higher-condition 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。

A superior area quality is certainly critical. Specs of area flatness are sometimes a lot better than . This assists to avoid equally scattering losses and wavefront distortions which may degrade the laser's beam high quality. On top of that, scratch and dig 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 considerably more than just a way to repair the laser-Energetic ions at specific positions in Area. Numerous properties in the host product are very important:

For quasi-three-degree laser get media or even 3-level get media, just one often must limit the length to a worth and that is also brief for efficient pump absorption, as reabsorption consequences would in any other case spoil the overall performance. For facet pumping, further concerns appear into Engage in; Other than efficient pump absorption, it's important to acquire a suitable spatial shape of the achieve profile.

For many motives, composite crystals are becoming common. These Have got a spatially various chemical composition and can be designed with Exclusive designs.

With that concept, one particular doesn't need to have a further saturable absorber crystal, to make sure that a person may possibly make a lot more compact Q-switched laser setups with lower inner parasitic losses. Even so, undesired Unwanted side effects may also manifest, including obtaining unwelcome valence states with the involved ions or Strength 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。
