These tables have only the commonest host crystals; numerous Many others exist, that happen to be a lot less frequently utilised.

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 �?ordinarily single crystals (monocrystalline optical products) �?which might be utilised as achieve media for sound-point out lasers. Normally, These are doped with either trivalent scarce earth ions or transition metallic ions.

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。

Which geometry, dopant and doping concentration on the gain medium are most useful count on several variables. The accessible pump source (sort of laser diode or lamp) and the envisaged pumping arrangement are very important variables, but the material itself also has some influence. For example, titanium–sapphire lasers ought to be pumped with substantial intensities, for which the shape of the transversely cooled rod, operated with rather modest pump and laser beam diameter, is much more proper 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 area good quality is of course important. Requirements of surface flatness are sometimes much better than . This helps to prevent equally scattering losses and wavefront distortions which could degrade the laser's beam high quality. Moreover, scratch and dig technical specs

The most feasible doping focus can rely strongly to the host substance and its fabrication approach.

Laser modeling and simulation can be utilized to reliably figure out the ideal crystal dimensions, doping density And maybe values of added parameters.

Those surfaces which are handed with the laser beam are Typically either oriented at Brewster's angle or have an anti-reflection coating.

主体材料中活性离子掺杂物的数量是关键因素。它影响了激光的效率和性能。过低的浓度可能导致低输出，过高的浓度可能导致消光效应，降低晶体的效率。

The medium ought to have a superior transparency (very low absorption and scattering) during the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this depends upon the standard of the material, based on particulars of your fabrication approach.

With That idea, one doesn't check here want an extra saturable absorber crystal, to ensure just one may possibly make far more compact Q-switched laser setups with decreased inner parasitic losses. Even so, undesirable Uncomfortable side effects may additionally happen, including obtaining undesired valence states in the associated ions or Strength transfers.
