These tables incorporate only the most common host crystals; quite a few Other folks exist, which might be a lot less often made use of.
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。
为了使激光器有效运作，需要有效管理运行过程中产生的热量。具有良好热导率的激光晶体可以更有效地散热，防止热透镜效应或断裂。
On top of that, some versatility is misplaced in experiments if just one can't Check out absorbers with distinctive thickness or doping concentration, for example, devoid of exchanging the laser crystal itself.
Which geometry, dopant and doping focus in the achieve medium are most advantageous depend on a number of components. The accessible pump source (kind of laser diode or lamp) and the envisaged pumping arrangement are important variables, but the material itself also has some influence. For instance, titanium–sapphire lasers should be pumped with substantial intensities, for which the shape of a transversely cooled rod, operated with relatively small pump and laser beam diameter, is much more ideal than e.
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。
A superior floor high quality is of course critical. Specifications of area flatness tend to be better than . This can help to prevent both equally scattering losses and wavefront distortions which might degrade the laser's beam high-quality. Furthermore, scratch and dig technical specs
亚稳态寿命也起着重要作用。较长的寿命允许更多的储能和实现粒子数反转的更高潜力，这对激光动作至关重要。
A handful of laser crystal resources have already been demonstrated wherever some saturable absorber content is incorporated for passive Q switching of the laser.

For quasi-3-stage laser attain media or simply three-level obtain media, one particular normally needs to limit the length to a worth that is as well limited for successful pump absorption, as reabsorption consequences would otherwise spoil the overall performance. For side pumping, further issues appear into Enjoy; Other than economical pump absorption, it is important to obtain an acceptable spatial condition with the get profile.
Different here crystalline elements are incredibly distinctive relating to their hardness as well as other Houses, which figure out with which solutions And the way quickly they can be Slice and polished with good quality.
GWU-Lasertechnik has more than 30 yrs of experience in distributing laser crystals. Pick GWU to take pleasure in our broad expertise As well as in-industry encounter!
There is certainly an array of crystalline media, which can be grouped according to special atomic constituents and crystalline structures. Some essential teams 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。
