These tables incorporate only the most common host crystals; numerous others exist, which are less often employed.
激光晶体的极化性能可能会影响输出激光束的质量和特性。有些激光晶体产生线性偏振光，这对某些应用可能有益。
Laser crystals are optical crystals �?usually single crystals (monocrystalline optical products) �?which might be applied as get media for good-condition lasers. In most cases, These are doped with either trivalent exceptional earth ions or changeover metal ions.

Which geometry, dopant and doping concentration of the attain medium are most advantageous count on numerous factors. The obtainable pump resource (type of laser diode or lamp) along with the envisaged pumping arrangement are crucial factors, but the material by itself also has some affect. Such as, titanium–sapphire lasers have to be pumped with large intensities, for which the form of a transversely cooled rod, operated with comparatively smaller pump and laser beam diameter, is a lot more proper than e.
GWU offers all popular laser crystals (Nd:YVO4, Nd:YAG, Yb:YAG and so on.) which has a broad number of specs. Besides the nicely-recognized materials, revolutionary crystals with exceptional Attributes like Yb:CALGO can open up new horizons for demanding laser applications. It does not matter whether unique pieces for R & D reasons are required or Expense-economical figures in compact, medium or significant batches with in-time shipping for that output line are essential: GWU’s committed provider helps to locate the best Main elements for the software.
A significant floor top quality is obviously important. Technical specs of floor flatness are frequently much better than . This allows to stop equally scattering losses and wavefront distortions which more info might degrade the laser's beam good quality. In addition, scratch and dig specs
The most possible doping focus can count strongly around the host material and its fabrication method.
Laser modeling and simulation may be used to reliably figure out the ideal crystal dimensions, doping density and possibly values of further 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。
It is clear that unique programs bring about very distinctive specifications on laser achieve media. Because of this, a wide selection of different crystals are used, and producing the right selection is essential for constructing lasers with the best possible effectiveness.

For several causes, composite crystals have gotten popular. These Use a spatially different chemical composition and might be created with Unique shapes.
Applying our promoting package deal, you are able to Display screen your emblem, further underneath your product or service description, and these will been seen by lots of photonics industry experts.
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。
