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。

激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。

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。

The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions and likewise the higher-condition life time.

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。

激光晶体的损伤阈值与其能承受的最大光强有关，而不会遭受物理或结构损伤。高损伤阈值对于确保高功率激光应用的耐久性和长寿命至关重要。

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。

Laser modeling and simulation can be employed to reliably establish the the best possible crystal dimensions, doping density and possibly values of further parameters.

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。

For quasi-3-amount laser get media or simply a few-amount attain media, one particular usually must Restrict the duration to a value that's much too small for successful pump absorption, as reabsorption results would in any other case spoil the functionality. For side pumping, supplemental criteria come into Engage in; Aside from successful pump absorption, it is important to obtain a suitable spatial shape of your acquire profile.

Diverse crystalline supplies are certainly unique regarding their hardness as well as other Attributes, which identify with which methods And exactly how simply they can be Reduce and polished with good quality.

The medium should have a higher transparency (low absorption and scattering) from the wavelength locations of pump and laser radiation, and superior optical more info homogeneity. To some extent, this relies on the standard of the material, determined by information in the fabrication process.

With that concept, 1 will not need to have a further saturable absorber crystal, making sure that a person may perhaps make more compact Q-switched laser setups with decrease internal parasitic losses. Nonetheless, unwelcome Negative effects may manifest, like obtaining undesirable valence states from the involved ions or Electrical power transfers.
