Laser crystals are optical crystals �?generally single crystals (monocrystalline optical elements) �?which are made use of as achieve media for reliable-state lasers. Usually, They may be doped with both trivalent exceptional earth ions or transition metallic ions.

Also, some flexibility is misplaced in experiments if a person simply cannot Check out absorbers with diverse thickness or doping concentration, such as, without exchanging the laser crystal by itself.

Which geometry, dopant and doping concentration of the achieve medium are most useful depend upon several components. The obtainable pump supply (kind of laser diode or lamp) and the envisaged pumping arrangement are important aspects, but the fabric itself also has some affect. As an example, titanium–sapphire lasers must be pumped with large intensities, for which the shape of the transversely cooled rod, operated with reasonably compact pump and laser beam diameter, is much more suitable than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

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 used to reliably determine the ideal crystal Proportions, doping density and possibly values of further parameters.

These surfaces which happen to be passed by the laser beam are normally possibly oriented at Brewster's angle or have an anti-reflection coating.

The medium ought to have a superior transparency (low absorption and scattering) inside the wavelength areas of pump and laser radiation, and fantastic optical homogeneity. To some extent, this depends on the standard of more info the fabric, based on details with the fabrication process.

There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some significant teams of crystals are:

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。
