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 focus from the get medium are most beneficial rely upon various variables. The available pump source (kind of laser diode or lamp) along with the envisaged pumping arrangement are crucial factors, but the fabric alone also has some affect. One example is, titanium–sapphire lasers should be pumped with higher intensities, for which the shape of a transversely cooled rod, operated with reasonably little pump and laser beam diameter, is more proper than e.

晶体的光学质量对激光器的有效运行至关重要。晶体中的缺陷或杂质可能导致光散射、吸收甚至损坏晶体。高光学质量确保了稳定和高质量的激光束。

A high area good quality is not surprisingly essential. Technical specs of floor flatness are sometimes a lot better than . This assists to prevent equally scattering losses and wavefront distortions which may degrade the laser's beam top quality. Also, scratch and dig specifications

g. a thin disk. As Yet another case in point, Q-switched lasers get to the next inhabitants density from the higher laser degree and they are hence more delicate to quenching results and Electricity transfer processes; for that reason, a reduce doping density is frequently suitable for these units. For top-electrical power lasers, reduce doping densities tend to be accustomed to limit the density of heat era, although thin-disk lasers function greatest with hugely doped crystals. Several laser products and solutions usually do not get to the entire general performance prospective for the reason that this kind of information haven't been correctly worked out.

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。

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 various purposes bring about really distinct needs on laser achieve media. For that reason, a wide selection of different crystals are utilized, and generating the proper alternative is important for developing lasers with optimum performance.

For several explanations, composite crystals are getting to be well-liked. These Have a very spatially different chemical composition and might be produced with special designs.

With That idea, click here a person isn't going to need an extra saturable absorber crystal, to ensure just one might make much more compact Q-switched laser setups with lower inside parasitic losses. On the other hand, undesired Unwanted effects can also take place, including acquiring undesired valence states of the involved ions or Vitality transfers.
