Distinctive crystalline supplies are really various regarding their hardness together with other Attributes, which determine with which methods And the way simply they are often Minimize and polished with good quality.
The medium ought to have a large transparency (low absorption and scattering) in the wavelength areas of pump and laser radiation, and very good optical homogeneity. To some extent, this is determined by the caliber of the fabric, based on particulars on the fabrication process.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions in addition to the higher-point out life span.
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 possible doping concentration can depend strongly to the host product and its fabrication approach.

In addition, some overall flexibility is dropped in experiments if one are unable to Check out absorbers with distinct thickness or doping focus, for example, without having exchanging the laser crystal itself.
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 with the achieve medium are most beneficial depend on many variables. The accessible pump source (type of laser diode or lamp) and also the envisaged pumping arrangement are important Nonlinear Crystal factors, but the fabric by itself also has some impact. For instance, titanium–sapphire lasers have to be pumped with superior intensities, for which the form of the transversely cooled rod, operated with reasonably compact pump and laser beam diameter, is more proper than e.
These tables include only the most typical host crystals; quite a few others exist, which can be a lot less frequently applied.
The commonest laser-Energetic exceptional earth ions and host media together with some normal emission wavelengths are proven in the next table:
A few laser crystal supplies have already been shown wherever some saturable absorber material is integrated for passive Q switching of the laser.
For several reasons, composite crystals have become well known. These have a spatially various chemical composition and might be built with special shapes.
There is certainly an array of crystalline media, which can be grouped in accordance to important atomic constituents and crystalline buildings. Some critical groups of crystals are:

GWU gives all widespread laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and many others.) which has a wide assortment of requirements. Moreover the properly-proven resources, modern crystals with exceptional properties like Yb:CALGO can open up new horizons for demanding laser apps. Despite no matter if particular person items for R & D applications are essential or Price tag-productive quantities in modest, medium or big batches with in-time shipping for the creation line are desired: GWU’s focused support helps you to locate the best core elements for your personal application.
It is obvious that diverse apps cause incredibly diverse requirements on laser obtain media. Due to this, a wide array of various crystals are made use of, and building the best option is important for developing lasers with optimum general performance.
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。
