These tables have only the most typical host crystals; lots of Other individuals exist, which happen to be less often utilised.

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。

Also, some adaptability is misplaced in experiments if one particular are unable to Check out absorbers with different thickness or doping concentration, as an example, with no exchanging the laser crystal by itself.

Which geometry, dopant and doping focus of your attain medium are most advantageous rely on a number of components. The available pump supply (sort of laser diode or lamp) along with the envisaged pumping arrangement are very important variables, but the material itself also has some impact. One example is, titanium–sapphire lasers must be pumped with large intensities, for which the shape of a transversely cooled rod, operated with rather compact pump and laser beam diameter, is much more appropriate than e.

Naturally, it's very fascinating that a supplied crystal excellent is generated continually, Though different laser layouts might have a distinct 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。

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。

Distinctive crystalline resources are very distinctive regarding their hardness and other Homes, which determine with which strategies And exactly how very easily they may be cut and polished with high quality.

The medium should have a higher transparency (low absorption and scattering) from the wavelength regions of pump and laser radiation, and good optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by facts from the fabrication process.

With That idea, one does not want an extra saturable absorber crystal, to ensure one particular may possibly make far more compact Q-switched laser setups with decrease inner parasitic losses. Nonetheless, undesirable Negative effects might also occur, which include acquiring unwanted valence states more info with the concerned ions or Power 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。
