These tables contain only the commonest host crystals; lots of Other individuals exist, that are a lot less often used.

These ions permit the crystal to amplify gentle for the laser wavelength by way of stimulated emission, when Electricity is equipped for the crystal through absorption of pump light (�?optical pumping

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。

Also, some flexibility is lost in experiments if one particular can not Check out absorbers with diverse thickness or doping concentration, by way of example, with out exchanging the laser crystal itself.

Which geometry, dopant and doping concentration from the attain medium are most beneficial depend on a number of aspects. The out there pump resource (style of laser diode or lamp) as well as the envisaged pumping arrangement are essential aspects, but the material by itself also has some influence. Such as, titanium–sapphire lasers ought to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with rather compact pump and laser beam diameter, is much more proper than e.

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。

激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

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。

It more info is apparent that various applications lead to extremely distinctive requirements on laser get media. This is why, a broad range of various crystals are utilised, and producing the correct choice is important for developing lasers with the best possible functionality.

The medium ought to have a higher transparency (very low absorption and scattering) from the wavelength regions of pump and laser radiation, and very good optical homogeneity. To some extent, this is dependent upon the caliber of the fabric, based on information from the fabrication system.

It might be oriented for in close proximity to perpendicular incidence from the laser beam, or at Brewster's angle. It could be fastened in some stable mount which also acts like a heat sink. Bigger crystals are frequently used for side pumping e.g. with superior-energy diode bars.

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。
