Diverse crystalline supplies are extremely unique concerning their hardness and various Homes, which identify with which techniques And just how easily they can be Minimize and polished with top quality.
The medium should have a large transparency (small absorption and scattering) within the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this depends on the quality of the material, determined by specifics from the fabrication course of action.
The host medium influences strongly the wavelength, bandwidth and transition cross-sections of pump and laser transitions as well as the upper-state lifetime.
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。
The most attainable doping focus can rely strongly over the host materials and its fabrication process.
By publishing the data, you give your consent to your probable publication of your respective inputs on our Web page As outlined by our regulations.

GWU-Lasertechnik has greater than thirty yrs of knowledge in distributing laser crystals. Pick GWU to take advantage of our broad awareness and in-area practical experience!
A substantial harm threshold concerning pulse fluence or peak intensity is often essential for top-Power amplifiers.
作为工业上使用较多的都是高掺钇铝石榴石，也就是说掺入不同的元素来达到不同的效果；作为工业激光，关注以下性能：
Which geometry, dopant and doping focus of your acquire medium are most beneficial count on many components. The available pump supply (kind of laser diode or lamp) as well as envisaged pumping arrangement are important variables, but the fabric by itself also has some affect. For example, titanium–sapphire lasers need to be pumped with substantial intensities, for which the shape of the transversely cooled rod, operated with relatively small pump and laser beam diameter, is more correct than e.
These tables incorporate only the commonest host crystals; a lot of others exist, which might be considerably less usually utilized.
Listed here you'll be able to post queries and comments. As far as they get acknowledged by the author, they're going to appear earlier mentioned this paragraph along with the author’s response. The creator will decide on acceptance dependant on selected standards. Effectively, The difficulty has to be of adequately broad curiosity.
A number of laser crystal materials are demonstrated the place some saturable absorber product is incorporated for passive Q switching of the laser.
For several good reasons, composite crystals are becoming common. These Possess a spatially different chemical composition and can be made with special shapes.
There may be a wide range of crystalline media, which can be grouped in accordance to special atomic constituents check here and crystalline constructions. Some vital groups of crystals are:
With that concept, a single isn't going to will need yet another saturable absorber crystal, to ensure that 1 might make much more compact Q-switched laser setups with reduced inner parasitic losses. Having said that, unwanted Unwanted side effects might also manifest, which include acquiring undesirable valence states in the involved ions or Electricity transfers.
GWU features all typical laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) by using a broad number of requirements. Aside from the properly-proven products, ground breaking crystals with superb properties like Yb:CALGO can open new horizons for demanding laser purposes. It does not matter whether or not specific parts for R & D reasons are required or Expense-efficient numbers in modest, medium or huge batches with in-time supply for that manufacturing line are needed: GWU’s focused company really helps to discover the most effective core parts for the software.
It is apparent that diverse purposes result in extremely diverse necessities on laser gain media. Because of this, a broad selection of various crystals are applied, and earning the proper selection is essential for setting up lasers with ideal effectiveness.
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。
