Unique crystalline materials are extremely unique regarding their hardness as well as other Houses, which decide with which solutions and how simply they may be Reduce and polished with high quality.
The medium should have a large transparency (small absorption and scattering) within the wavelength areas of pump and laser radiation, and superior optical homogeneity. To some extent, this depends upon the caliber of the fabric, based on details in the fabrication course of action.
The host medium influences strongly the wavelength, bandwidth and changeover cross-sections of pump and laser transitions and likewise the higher-condition life time.
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 depend strongly over the host materials and its fabrication system.

GWU-Lasertechnik has much more than 30 many years of experience in distributing laser crystals. Pick out GWU to reap the benefits of our extensive understanding As well as in-subject knowledge!
A large destruction threshold regarding pulse fluence or peak intensity might be important for prime-energy 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 from the get medium are most advantageous depend upon quite a few elements. The readily available pump resource (kind of laser diode or lamp) along with the envisaged pumping arrangement are crucial elements, but the material by itself also has some impact. For example, titanium–sapphire lasers need to be pumped with substantial intensities, for which the shape of the transversely cooled rod, operated with rather little pump and laser beam diameter, is more acceptable than e.
It might be oriented for in the vicinity of perpendicular incidence in the laser beam, or at Brewster's angle. It can be set in a Nonlinear Crystal few sound mount which also acts like a heat sink. More substantial crystals usually are employed for aspect pumping e.g. with significant-electric power diode bars.
The most common laser-Lively scarce earth ions and host media along with some standard emission wavelengths are proven in the following desk:
Some laser crystal components are actually demonstrated wherever some saturable absorber product is integrated for passive Q switching of the laser.
For different explanations, composite crystals are becoming well known. These have a spatially various chemical composition and will be built with Unique designs.
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。
With That idea, a person does not need an additional saturable absorber crystal, to ensure that 1 might make much more compact Q-switched laser setups with reduce internal parasitic losses. Nevertheless, unwanted Negative effects could also manifest, which include acquiring undesirable valence states from the involved ions or Electrical power transfers.
GWU provides all common laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG etcetera.) that has a broad variety of technical specs. Aside from the effectively-established products, modern crystals with exceptional properties like Yb:CALGO can open up new horizons for demanding laser applications. It doesn't matter whether unique items for R & D purposes are essential or Price-successful numbers in smaller, medium or big batches with in-time supply for your generation line are required: GWU’s committed service helps you to locate the very best Main factors to your software.
It is obvious that unique purposes lead to really diverse prerequisites on laser gain media. Because of this, a broad assortment of various crystals are utilised, and building the right option is essential for constructing lasers with optimum efficiency.
