激光晶体是固态激光器的核心。它们是光放大发生的媒介，产生激光束。在这篇全面指南中，我们深入探讨激光晶体的世界。
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。
This is easy to carry out: just find the lock icon in front of the URL within the tackle bar and drag that into the bookmark toolbar Along with the mouse. In case you find the bookmark entry too extended, you could right-click it to edit the textual content, e.g. using "RP Enc" as opposed to "RP Photonics Encyclopedia".
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。
Naturally, it's very fascinating that a supplied crystal good quality is made constantly, Even though distinctive laser designs might have a special sensitivity to materials parameters.
The most achievable doping focus can depend strongly to the host materials and its fabrication strategy.
Laser modeling and simulation can be utilized to reliably determine the ideal crystal dimensions, doping density And maybe values of extra parameters.
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-three-stage laser achieve media or perhaps a few-degree attain media, just one frequently really should limit the size to a price which is far check here too quick for economical pump absorption, as reabsorption results would otherwise spoil the effectiveness. For side pumping, more concerns appear into play; Apart from economical pump absorption, it is vital to obtain an appropriate spatial form in the achieve profile.
Various crystalline products are really various relating to their hardness and other Qualities, which ascertain with which solutions And the way very easily they are often Slice and polished with top quality.
GWU-Lasertechnik has much more than thirty several years of knowledge in distributing laser crystals. Pick out GWU to get pleasure from our wide know-how As well as in-area working experience!
There is certainly an array of crystalline media, which may be grouped in accordance to big atomic constituents and crystalline buildings. Some vital groups of crystals are:
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。
