Blog Article
These tables comprise only the most common host crystals; numerous Other individuals exist, which might be considerably less often utilised.
Below you may submit thoughts and responses. In terms of they get accepted because of the author, they are going to show up previously mentioned this paragraph together with the author’s reply. The author will decide on acceptance determined by particular conditions. Effectively, The difficulty should be of sufficiently wide fascination.
Laser crystals are optical crystals �?typically single crystals (monocrystalline optical products) �?that happen to be utilised as gain media for stable-state lasers. Usually, They're doped with both trivalent unusual earth ions or transition steel ions.

Which geometry, dopant and doping focus on the obtain medium are most useful count on many things. The out there pump supply (type of laser diode or lamp) plus the envisaged pumping arrangement are important things, but the material itself also has some influence. As an example, Laser Crystal titanium–sapphire lasers should be pumped with significant intensities, for which the shape of a transversely cooled rod, operated with fairly little pump and laser beam diameter, is much more acceptable than e.
激光晶体由发光中心和基质晶体两部分组成。大部分激光晶体的发光中心由激活离子构成，激活离子部分取代基质晶体中的阳离子形成掺杂型激光晶体。激活离子成为基质晶体组分的一部分时，则构成自激活激光晶体。
Obviously, it's very appealing that a given crystal quality is developed persistently, Despite the fact that various laser styles can have a special sensitivity to substance parameters.
The most achievable doping focus can count strongly within the host material and its fabrication strategy.
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。
It is obvious that distinctive purposes bring about really various requirements on laser obtain media. Because of this, a broad vary of different crystals are applied, and making the ideal selection is important for constructing lasers with ideal effectiveness.
主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。
The medium ought to have a significant transparency (lower absorption and scattering) from the wavelength locations of pump and laser radiation, and excellent optical homogeneity. To some extent, this is determined by the standard of the fabric, based on details of the fabrication process.
Applying our advertising and marketing deal, you'll be able to display your symbol, further more beneath your item description, and these will been observed by quite a few photonics professionals.
激光晶体（laser crystal），可将外界提供的能量通过光学谐振腔转化为在空间和时间上相干的具有高度平行性和单色性激光的晶体材料。是晶体激光器的工作物质。
