These tables include only the most common host crystals; quite a few Other individuals exist, which can be less commonly utilized.
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 �?typically one crystals (monocrystalline optical resources) �?which might be applied as attain media for sound-state lasers. Most often, they are doped with either trivalent scarce earth ions or transition metallic ions.
激光晶体中活性离子的作用是什么？ 活性离子在激光晶体中负责通过受激发射产生激光光线。
Which geometry, dopant and doping focus from the get medium are most advantageous depend on a number of aspects. The readily available pump supply (style of laser diode or lamp) and also the envisaged pumping arrangement are essential variables, but the material itself also has some affect. One example is, titanium–sapphire lasers need to be pumped with large intensities, for which the form of the transversely cooled rod, operated with somewhat tiny pump and laser beam diameter, is much more suitable 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 higher surface high-quality is needless to say significant. Technical specs of area flatness will often be much better than . This helps to avoid both scattering losses and wavefront distortions which can degrade the laser's beam high-quality. On top of that, scratch and dig requirements
The utmost feasible doping concentration can count strongly within the host product and its fabrication strategy.
激光晶体的效率在很大程度上依赖于某些属性，这些属性不仅限于其基本组成。这些特性决定了产生的激光光束的质量和随后的应用。

It is obvious that distinctive applications cause extremely different requirements on laser get media. Because of this, a broad assortment of various crystals are utilised, more info and generating the right preference is important for constructing lasers with optimum efficiency.
材料 激光晶体 晶体生长 光学性能 稀土离子 过渡族离子 resources laser crystal crystal progress optical general performance scarce earth ions transition team ions
The medium ought to have a substantial transparency (reduced absorption and scattering) while in the wavelength locations of pump and laser radiation, and fantastic optical homogeneity. To some extent, this relies on the quality of the fabric, determined by aspects of the fabrication procedure.
With That idea, a single does not will need yet another saturable absorber crystal, making sure that 1 may make far more compact Q-switched laser setups with lessen internal parasitic losses. Nevertheless, undesired Unwanted side effects may additionally occur, like getting unwanted valence states from the concerned ions or Electricity transfers.
