The most common laser-Energetic scarce earth ions and host media together with some regular emission wavelengths are shown in the subsequent desk:

Laser crystals are optical crystals �?typically single crystals (monocrystalline optical supplies) �?which happen to be made use of as gain media for good-state lasers. In most cases, They are really doped with either trivalent exceptional earth ions or changeover metal ions.

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 vitally fascinating that a presented crystal top quality is produced constantly, Even though unique laser patterns might have a different sensitivity to content parameters.

g. a thin disk. As An additional instance, Q-switched lasers achieve a greater population density in the higher laser degree and are hence far more sensitive to quenching effects and Vitality transfer processes; consequently, a lower doping density is frequently suitable for these more info products. For prime-electrical power lasers, reduced doping densities are frequently used to Restrict the density of warmth era, While slim-disk lasers do the job greatest with remarkably doped crystals. Quite a few laser solutions tend not to get to the total efficiency probable due to the fact such aspects haven't been effectively labored out.

Laser modeling and simulation can be used to reliably identify the optimum crystal dimensions, doping density And maybe values of extra parameters.

热膨胀和收缩系数对确定激光晶体的热透镜特性至关重要。最小化热透镜效应对于在广泛的操作温度范围内保持光束质量至关重要。

Different crystalline resources are incredibly distinct concerning their hardness and various properties, which figure out with which techniques And just how conveniently they may be cut and polished with good quality.

The medium should have a superior transparency (lower absorption and scattering) while in the wavelength regions of pump and laser radiation, and superior optical homogeneity. To some extent, this relies on the caliber of the material, based on specifics of the fabrication approach.

There may be a wide array of crystalline media, that may be grouped in accordance to big atomic constituents and crystalline structures. Some crucial 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。
