These tables comprise only the most typical host crystals; quite a few Other people exist, which happen to be much less usually made use of.

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。

Laser crystals are optical crystals �?usually one crystals (monocrystalline optical elements) �?which happen to be used as acquire media for sound-point out lasers. Generally, They are really doped with possibly trivalent exceptional earth ions or transition steel ions.

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 achieve medium are most beneficial depend on a number of variables. The accessible pump source (sort of laser diode or lamp) and also the envisaged pumping arrangement are important things, but the material alone also has some influence. For instance, titanium–sapphire lasers ought to be pumped with substantial intensities, for which the form of the transversely cooled rod, operated with reasonably little 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。

The most attainable doping focus can depend strongly about the host materials and its fabrication technique.

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。

For quasi-a few-degree laser gain media or simply 3-amount achieve media, a single frequently ought to Restrict the duration to a value which happens to be way too short for successful pump absorption, as reabsorption effects would normally spoil the overall performance. For aspect pumping, supplemental factors appear into Participate in; Apart from successful pump absorption, it is important to obtain a suitable spatial shape of your acquire profile.

The medium must have a high transparency (small absorption and scattering) from the wavelength regions of pump and click here laser radiation, and superior optical homogeneity. To some extent, this will depend on the quality of the fabric, determined by information of your fabrication process.

Applying our advertising package deal, you could display your symbol, even more beneath your item description, and these will been found by numerous photonics experts.

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。
