The most typical laser-Lively uncommon earth ions and host media together with some normal emission wavelengths are demonstrated in the next table:

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 �?normally one crystals (monocrystalline optical components) �?which happen to be employed as gain media for sound-point out lasers. Normally, They are really doped with either trivalent unusual earth ions or transition metal ions.

Moreover, some versatility is shed in experiments if 1 are not able to Check out absorbers with distinctive thickness or doping concentration, as an example, devoid of exchanging the laser crystal alone.

This is easy to try and do: just find the lock icon before the URL in the tackle bar and drag that into the bookmark toolbar With all the mouse. In the event you discover the bookmark entry also lengthy, you can right-simply click it to edit the textual content, e.g. utilizing "RP Enc" instead of "RP Photonics Encyclopedia".

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。

Not surprisingly, it get more info is vitally attractive that a supplied crystal good quality is made constantly, While diverse laser patterns might have a unique sensitivity to materials parameters.

The utmost feasible doping focus can depend strongly about the host materials and its fabrication process.

A couple of laser crystal products have already been shown where by some saturable absorber materials is included for passive Q switching of a laser.

Those surfaces which are handed through the laser beam are Ordinarily both oriented at Brewster's angle or have an anti-reflection coating.

Various crystalline products are quite different concerning their hardness and other Houses, which figure out with which procedures and how easily they are often Slice and polished with good quality.

The medium should have a superior transparency (very low absorption and scattering) inside the wavelength locations of pump and laser radiation, and very good optical homogeneity. To some extent, this depends upon the standard of the material, based on specifics of your fabrication method.

There is certainly a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline buildings. Some important teams of crystals are:

人造红宝石激光晶体是首次实现激光输出的材料。可用焰熔法、提拉法或助熔剂法生产单晶。用提拉法容易获得大尺寸优质晶体。
