These tables contain only the most typical host crystals; many Many others exist, which can be much less frequently applied.
These ions enable the crystal to amplify light at the laser wavelength by way of stimulated emission, when energy is supplied to the crystal by using absorption of pump gentle (�?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。

Which geometry, dopant and doping concentration of your achieve medium are most beneficial count on numerous components. The offered pump supply (kind of laser diode or lamp) as well as the envisaged pumping arrangement are crucial factors, but the material by itself also has some impact. Such as, titanium–sapphire lasers must be pumped with large intensities, for which the form of the transversely cooled rod, operated with fairly smaller pump and laser beam diameter, is more ideal 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。
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。
激光晶体的核心由固态晶体材料组成，通常掺杂了某些能够通过受激发射产生光放大的离子。这些离子的性质对激光晶体的性能起决定作用。
It is obvious that unique applications result in really diverse demands on laser achieve media. This is why, a broad assortment of different crystals are utilized, and creating the proper choice is important for setting up lasers with optimum performance.
Different crystalline elements are quite various relating to their hardness as well as other Houses, which determine with which solutions And the way quickly they may be Lower and polished with high quality.
The medium must have a high transparency (very low absorption and scattering) while in the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the standard of the material, based on particulars with the fabrication procedure.
It could be oriented for near perpendicular incidence from the laser beam, or at Brewster's angle. It can be mounted in a few reliable mount check here which also functions to be a heat sink. Bigger crystals are generally used for facet pumping e.g. with superior-electric power diode bars.
