The most common laser-Energetic rare earth ions and host media along with some regular emission wavelengths are proven in the next desk:

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 solitary crystals (monocrystalline optical products) �?that happen to be applied as attain media for reliable-state lasers. Typically, They may be doped with both trivalent rare earth ions or changeover steel ions.

Which geometry, dopant and doping focus with the acquire medium are most advantageous count on many elements. The obtainable pump resource (kind of laser diode or lamp) as well as the envisaged pumping arrangement are important aspects, but the material itself also has some influence. By way of example, titanium–sapphire lasers have to be pumped with significant intensities, for which the form of the transversely cooled rod, operated with rather small pump and laser beam diameter, is more proper than e.

Obviously, it is vitally desirable that a given crystal top quality is made continuously, although different laser models may have a distinct sensitivity to materials parameters.

g. a skinny disk. As Yet another case in point, Q-switched lasers arrive at a greater population density in the higher laser amount and so are for that reason additional delicate to quenching effects and energy transfer processes; consequently, a reduced doping density is usually appropriate for these products. For top-electricity lasers, decreased doping densities will often be used to Restrict the density of heat generation, Despite the fact that Laser Crystal skinny-disk lasers work best with remarkably doped crystals. Many laser solutions will not get to the entire effectiveness likely mainly because these types of specifics have not been adequately labored out.

Some laser crystal products are actually shown wherever some saturable absorber product is included for passive Q switching of the laser.

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 obvious that different apps bring about extremely various specifications on laser gain media. For that reason, a broad assortment of various crystals are utilised, and producing the proper option is essential for constructing lasers with optimum functionality.

Distinctive crystalline elements are quite various regarding their hardness and other Homes, which determine with which techniques And just how effortlessly they can be Lower and polished with good quality.

The medium should have a high transparency (low absorption and scattering) within the wavelength areas of pump and laser radiation, and great optical homogeneity. To some extent, this relies on the standard of the fabric, based on specifics on the fabrication process.

With that concept, one does not have to have an extra saturable absorber crystal, to ensure just one may make more compact Q-switched laser setups with reduced inner parasitic losses. Even so, undesired Unwanted side effects can also manifest, which include getting undesired valence states from the involved ions or Electrical power 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。
