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 �?commonly single crystals (monocrystalline optical elements) �?which can be made use of as obtain media for stable-state lasers. Most often, They're doped with either trivalent uncommon earth ions or changeover 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 useful count on many components. The available pump source (kind of laser diode or lamp) plus the envisaged pumping arrangement are very important elements, but the material itself also has some impact. For example, titanium–sapphire lasers ought to be pumped with large intensities, for which the shape of the transversely cooled rod, operated with reasonably smaller pump and laser beam diameter, is 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。

Obviously, it is extremely desirable that a supplied crystal excellent is developed constantly, Whilst diverse laser patterns might have a unique sensitivity to materials parameters.

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。

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

For quasi-a few-degree laser gain media or simply 3-amount obtain media, one generally has to Restrict the length to a price which is much too quick for successful pump absorption, as reabsorption effects would normally spoil the overall performance. For aspect pumping, supplemental concerns appear into Participate in; In addition to productive pump absorption, it can be crucial to acquire an acceptable spatial condition of the acquire profile.

The medium must have a higher transparency (small absorption and scattering) while in the wavelength regions of pump and laser radiation, and fantastic optical homogeneity. To some extent, this is determined by the standard of the material, based on particulars with the fabrication procedure.

With That idea, just one won't need yet another saturable absorber crystal, in order that just one could make a lot more compact Q-switched laser setups with lessen interior parasitic losses. Nonetheless, undesired Unintended effects can also happen, such as more info obtaining undesired valence states from the included ions or Vitality transfers.

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。
