These tables consist of only the most common host crystals; quite a few Other people exist, which happen to be significantly less routinely used.

Here you'll be able to submit issues and opinions. In terms of they get recognized via the author, they'll seem earlier mentioned this paragraph along with the writer’s response. The writer will settle on acceptance according to certain criteria. Effectively, The difficulty have to be of sufficiently wide fascination.

激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。

Which geometry, dopant and doping focus with the get medium are most beneficial depend on several factors. The accessible pump resource (form of laser diode or lamp) along with the envisaged pumping arrangement are essential elements, but the fabric by itself also has some impact. One example is, titanium–sapphire lasers must be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with relatively small pump and laser beam diameter, is a lot 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。

量子效率是发射光子数量与吸收光子数量的比率。高量子效率表明更大部分吸收能量被转化为激光光束，有助于提高激光的整体效率。

For quasi-a few-degree laser gain media or simply 3-level get media, a single frequently really should limit the duration to a value that's much too quick for economical pump absorption, as reabsorption effects would normally spoil the performance. For aspect pumping, supplemental concerns arrive into Enjoy; Other than economical pump absorption, it's important to acquire a suitable spatial form of your acquire profile.

The medium must have a substantial transparency (minimal absorption and scattering) within the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this depends upon the standard of the material, based on particulars with the fabrication method.

It might be oriented for around perpendicular incidence with the laser beam, or at Brewster's angle. It could be preset in certain good mount which also functions for a warmth sink. More substantial crystals are frequently employed for aspect pumping e.g. with large-electrical power diode bars.
